Paris Hilton has branded Deadmau5 an attention seeker.
The 33-year-old socialite hit back at the DJ on Twitter after he called her a "straight up a**" for trying to carve out a career in the music industry and earning $1 million for "playing a CD at a club."
In a post on his blog, the 'Ghosts 'n' Stuff' hitmaker wrote: "I remember back when, at the cosmo in vegas, she attended, and i guess i was accommodating (as far as that usually goes for me) i could see she was having a fun time, liked the music, and just wanted to be a part of it all... so of course, why not... even i couldn't hate on that (sic).
"But, let's get real here for a second... There's being invovled / enthusiastic about something... and then theres just being a straight up a** (sic)."
The 33-year-old musician - real name Joel Zimmerman - said Paris was insulting him and his colleagues by encroaching on their scene and calling herself a professional, as they have "invested their entire lives to their careers."
He added: "so paris, thank you... were actually not even mad youre enthusiatic about electronic music... we love that youre a part of our party. But please, get the f**k back in your go kart. No need to prove that you found someone stupid enough to consider paying you a million dollars for something the world knows you arent... because here's what you actually are to everyone who knows better.. ticket sales. nothing more (sic)."
He also suggested the former reality TV star only became a DJ because she once dated DJ AfroJack.
But the blonde beauty quickly laughed off his rant, tweeting: "I find it hilarious when others try to badmouth me in order to get attention. Sorry that I'm #Killingit while doing what I love & live for (sic)."

Sam Smith loves the idea of getting married and having children.
The 'Stay With Me' hitmaker, who is currently single, admits he is looking forward to settling down in the future and would love to open a coffee shop in Italy.
The 22-year-old singer told Teen Vogue: "The idea of having a house, a kid, a husband, and a dog...I love that. I also really want to open a coffee and flower shop one day, probably in Italy."
The British star, who has been openly gay for many years, wrote much of his debut album, 'In The Lonely Hour,' about unrequited love, but he will always "treasure" the experience.
He said: "I fell in love with someone last year, and he didn't love me back. I deleted him off of WhatsApp, and it felt like I'd just broken up with him. On the record you can hear heartbreak, and there's a beauty in that I will always treasure."
He added: "With the whole gay thing, I've had zero reaction, which says something beautiful about our generation and how things are getting a little bit better."
But Sam still gets very emotional while performing tracks from the record.
He said: "I stand onstage and I wanna cry for the entire thing because people know my business. You all know me. You can read as many interviews as you want, but if you put on my record, I'm telling you, that is me."

Keira Knightley never got an invite to her prom.
The 'Begin Again' actress had to attend her high school dance with a girlfriend because no boys asked her to be their date.
Talking to the Huffington Post, Keira explained: "We don't really have proms in England, not in the American way. So I actually turned up late and went with one of my best girl friends, because nobody asked either of us to prom. We were each other's dates, which was fun.
"She's great, she's one of my best mates still. We had a lovely time and we didn't care that nobody had asked us, we asked each other."
The 29-year-old screen beauty also admitted that she "hated" being a teenager so it was particularly interesting for her to play her character Megan in her new film 'Laggies', because her alter ego desperately wants to cling onto her youth.
Keira said: "It's a funny thing really because I hated being a teenager and I was never really interested in doing teenage films. I always just wanted to be out of that whole period of my life.
"So I sort of liked playing somebody who had a completely different experience, who absolutely loved it and identified with that part of their life as being the period."
Keira stars in 'Laggies' with Chloë Grace Moretz and
Sam Rockwell.

Daniel Radcliffe has never been on The Making of Harry Potter tour.
The 25-year-old actor is yet to visit the Warner Bros. Studio Tour in Watford, Hertfordshire, South East England, despite being the main star of the eponymous franchise.
The 'Horns' star - who plays the boy wizard in eight films based on the books by J.K. Rowling - has avoided the attraction because he is worried his presence would cause a "commotion".
During an appearance on 'The Jonathan Ross Show', which airs on ITV tomorrow (25.10.14), he said: "There's never been a good time for me to go back when it wouldn't cause some commotion or something but ... Hopefully I'll get to do a movie there and then just slip in ... It's amazing how little disguises help and then how ridiculous you feel once you've been found in a disguise."
Daniel - who worked on the films from the age of 11 to 22 - insists starring in the global phenomenon isn't his proudest achievement and claims learning to dance is top of his list.
The actor - who recently starred in 'The Cripple of Inishmaan' at the Cort Theatre on Broadway in New York - explained: "I was the blankest canvas my dance teacher had ever seen... he taught me to dance, I owe it all to him.
"I don't boast about stuff generally speaking - it's not really me - but learning to dance on Broadway and dancing in a Broadway show is probably the thing I'm absolutely proudest of."

Vanessa Hudgens and Austin Butler celebrated their third anniversary at a vineyard.
The couple - who started dating in October 2011 - took a romantic trip to Sonoma Valley in northern California for the occasion and were spotted enjoying themselves at the newly opened Hamel Family Wines.
A source told Life & Style Weekly magazine: "They enjoyed a private tour of the grounds, including a barrel tasting in the caves with winemaker John Hamel, and a private reserve tasting with proprietor George Hamel III. It was really special, they loved it!"
The 25-year-old actress has recently been supporting the 'Carrie Diaries' star following the tragic death of his mother last month, who had been battling cancer.
After her passing Austin, 25, wrote on Twitter: "Lori Butler, my mom, my hero, & my best friend passed away this morning. Lets all celebrate her. I love you and will miss you every day Mom (sic)"
Vanessa replied: "#ripLoriButler #celebrateLori Spread the love for Lori. (sic)"

Jourdan Dunn has admitted she got a reality check when her son was diagnosed with sickle cell anaemia.
The 24-year-old model's four-year-old child Riley was born with the condition - in which there aren't enough healthy red blood cells in the body to carry adequate oxygen - but she was shocked when doctors discovered he had the disease when he was just six-months-old.
She told Vogue magazine: "I knew there was a possibility that I was carrying a sickle cell baby because both his dad and I have the trait. But of course, I always had it in my head, 'No, not my baby. That's not going to happen to me.' "
Jourdan designed a Cell for Gratitude necklace with brand Tuleste to raise funds for the charity SCDAA (Sickle Cell Disease Association of America) and recently threw a star-studded party at New York Fashion Week to raise awareness, where guests included her close pals Cara Delevingne, Rihanna and Karlie Kloss.
She said: "I was so overwhelmed by it all. Before a model, I am a mother. Now, I do my job for Riley."

London's Science Museum is "honoured" Queen Elizabeth chose the venue to send her first ever tweet.
The 88-year-old monarch made history earlier today (24.10.14) when she sent her first ever message on social networking site Twitter during a visit to the major tourist attraction with her husband Prince Philip, where they were opening the building's new Information Age gallery.
A tweet on the Science Museum's account in response to Elizabeth's message on the official account of the British Monarch read: "@BritishMonarchy We're honoured The Queen chose to open our Information Age gallery by sending her first tweet #smInfoAge #TheQueenTweets (sic)"
Earlier in the day, the queen wrote: "It is a pleasure to open the Information Age exhibition today at the @ScienceMuseum and I hope people will enjoy visiting. Elizabeth R."
Following the historic moment, the British Monarchy account confirmed the message had been sent by the royal, writing: "The last tweet was sent personally by The Queen from her official Twitter account @BritishMonarchy #TheQueenTweets"
Shortly before the queen made history with the tweet, museum director Ian Blatchford invited her to aptly mark the opening of the establishment's Information Age gallery by sending the message.
He said: "I mentioned earlier that Queen Victoria took a great interest in the invention of the telephone, and Your Majesty has followed in this tradition of embracing new technology.
"You made the first live Christmas broadcast in 1957 and an event relished by historians took place [on March 26, 1976] when you became the first monarch to send an email, during a visit to the Royal Signals and Radar Establishment. May I now invite you to join me so that you may send your first tweet."
The message is said to have been pre-typed on a tablet computer leaving the monarch to simply press the send button.
However, the queen's tweet may not have gone down too well with her grandson Prince Harry after he recently admitted to "quite hating" Twitter for its "invasion of privacy".
Speaking about whether he would use Twitter during the recent Invictus Games, he said: "I would love to get involved and go on social media, and if it was for causes like this I really would.
"The issue for myself and my family, put quite simply, is that it's very hard for me to tweet about the Invictus Games and tweet about something that means a lot to me, whereas I at the same time really quite hate Twitter by the invasion of privacy. I think you all understand what I'm talking about."
The queen is not the only royal to have tweeted as Princess Beatrice (@yorkiebea) has had an account on the social networking account since November 2011, managing to stay under the radar for many months before the account was given the official Twitter 'blue tick' to recognise it is in fact Beatrice's page.
Her mother Sarah Ferguson is also a keen tweeter and has been on Twitter since May 2011 under the handle @SarahTheDuchess.

Naomi Campbell is convinced the Ebola virus is a plague sent by God.
The supermodel - who is organising two charity fashion shows in aid of victims of the deadly disease - is "terrified" of catching the illness and is convinced the epidemic was predicted in the Christian Bible.
She said: "I'm terrified. It was written in the Bible, it was in the Bible there was going to be a plague and this is it, I think this is it."
And the 44-year-old British star is taking special precautions to minimise her chances of being stricken with the virus when she travels for her fashion work.
During her appearance on 'Celebrity Gogglebox', she said: "I want a space suit, do you think we can go to NASA and buy a space suit? It's scary s**t"
"I don't care what people laugh at, I went on a plane the other day and I wore my two masks, I've got to feel protected, I don't give a damn. I got my Clorox bleach and my rubber gloves and I sprayed down my seat and that's what I'm going to do on every flight from now on."
When Noel Gallagher asked, "Are you seriously telling me you went on a plane with bleach and two f***ing masks?", she replied, "Yes, one over my nose and one over my mouth. I had my latex gloves, sprayed down the seat, cleaned it down."
Her friend Kate Moss then mocked her, laughing: "And then when an air hostess came over, she was like, 'No, don't come near me.' "

William H. Macy has "fallen in love" with the film industry "all over again".
The 64-year-old actor recently made his directorial debut on upcoming comedy-drama 'Rudderless' and he's confessed he's glad he's making the change so late in life because it's renewed his love for movies.
He explained: "We all know directors who, having done the most brilliant work early in their career, eventually start to flag and get worse.
"They lose touch with the world and work in a vacuum. But because I'm starting in my 60s, I'm approaching it with a humility I wouldn't otherwise have had.
"On the one hand, I'm scared half to death, which means that I listen to people. And on the other, it's as though I've fallen in love with the business all over again."
The 'Wild Hogs' star added: "So I'm scared and horny. I'm like a 14-year-old boy."
Macy also revealed the reason behind his decision to take a step back from acting.
He told The Guardian newspaper: "My career is what is it, but I felt that I'd exhausted the fun in acting. I still get a good role every once in a while, but a lot of it is yeoman work.
"I'm usually being called on to play somebody's uncle, or the elderly senator. And that's fine, it's money. But it's not that scintillating any more."

Benedict Cumberbatch has refused to deny rumours he will make an appearance in 'Star Wars Episode VII'.
There has been widespread speculation Cumberbatch, 38, will star in the much-anticipated movie alongside the likes of Harrison Ford, Carrie Fisher and Mark Hamill.
Speaking on 'The Graham Norton Show', Cumberbatch was asked whether he is to appear in the film, to which he replied: "No comment."
The Hollywood star, who has previously worked with 'Star Wars Episode VII' director JJ Abrams on 'Star Trek Into Darkness', revealed he's visited the set of the new film but was reluctant to disclose any further details.
Cumberbatch said: "I went to the set. It was incredible. I probably shouldn't be saying these things."
Speaking about his next film, Cumberbatch recently said he would happily dress in drag to play Queen Elizabeth II.
Cumberbatch played the part of gay mathematician Alan Turing in the WW2 thriller 'The Imitation Game' and joked he would be up for playing the British monarch, even though he's a man.
When asked why it took so long for authorities to pardon his character - who was prosecuted for his sexuality in 1952 - he said: "Why couldn't it have been earlier? I don't know. I'm not the Queen or David Cameron.
"Maybe those will be my next roles. I'd like to see me in that frock."

Rachel Riley misses her 'Strictly Come Dancing' training.
The 'Countdown' beauty has confessed that although she's now dating her professional dance partner from the 2013 series, Pasha Kovalev, she misses learning the basic steps that make up the individual dances more so than taking part in the contest itself.
She exclusively told BANG Showbiz: "I wish I was still learning to dance because I enjoyed learning to dance but I wouldn't want to be in front of those judges again because that's terrifying, with the voiceover saying your names and then the dance.
"They can keep that part but I wouldn't mind the outfits and the training."
The 28-year-old star - whose boyfriend is now competing in the BBC One dance contest with former 'Xtra Factor' presenter Caroline Flack - also has some advice for the celebrities taking part this year, who include 'EastEnders' actor Jake Wood and The Saturdays singer Frankie Bridge.
Rachel said: "Just enjoy it, I mean I'm sure they all are anyway, but it all goes by in a flash. Unfortunately you don't get to choose when you finish and each week now people are going and each week unexpected people are in the dance-off so just appreciate it while it lasts and just go for it so you have no regrets afterwards."

James Nesbitt is enjoying celibacy since splitting from his wife.
The 49-year-old actor split from his wife of 19-years, Sonia Forbes-Adam - with whom he has daughters Peggy and Mary - last year and has confessed he's been enjoying single life ever since.
He told the Daily Telegraph newspaper: "My family is living in Herne Hill and I'm renting in Dulwich.
"You'll find me in the pub twice a week. I'm enjoying the single life, and, oh yes, the celibate life."
Meanwhile, the 'Cold Feet' star previously admitted he's been living an "isolated life" in order to get into character for his latest role in new BBC One drama 'The Missing', in which he stars as the father of a child who has been abducted.
He explained: "I tried to live as isolated a life as I could ... And I tried not to be social with the crew or cast. I would go out and eat by myself..."
And James believes the intense storylines and not being able to see his children while filming in Brussels actually affected his mental state.
He added: "What would occasionally get to me was the sense of isolation, the sense of being on your own. Being away from my kids, that was not easy. But the strengths of it were almost the negatives of it. It was very helpful for the piece. But certainly at times it was, ah, difficult."
