Miley Cyrus is releasing a MAC lipstick which will raise money for HIV sufferers.
The 'We Can't Stop' singer has teamed up with the cosmetic company to bring out her own branded Viva Glam lipstick in early 2015 and the proceeds will go to the MAC AIDS Fund charity.
She announced the collaboration on her Twitter page, writing: "Going #VIVAGLAM with @MACcosmetics. Look for my lipstick in early 2015 ... Every $ from the sales of my #VIVAGLAM will go to @MACAIDSFund to help those affected by HIV! (sic)"
The MAC AIDS Fund's mission statement is "to serve people of all ages, races and sexes affected by HIV/AIDS. We fund bold, visionary and brave trailblazers determined to end the epidemic".
Miley's charity work proves she's more than just a "walking joke", as she recently referred to herself.
The 21-year-old pop star - famous for her wild on stage antics -said: "If I wasn't here I'd like to be doing some sort of stand up comedy, so I think that this is my way of doing that. I am the joke. Look at me! I'm a walking joke ... I just kind of grew up in the pop world, so fame and money, I kind of know what they give you, which isn't a lot ... even though people think it's kind of everything.
"I just decided, about a year ago, that my whole life goal was just to be happy all the time."

Sir Michael Caine doesn't worry about his carbon footprint because he was "so poor for so long".
The Oscar-winning actor - who stars in new sci-fi film 'Interstellar' alongside the likes of Anne Hathaway and Matthew McConaughey - was raised in London, and he says his modest start in life means he doesn't fret about over-indulging now.
Appearing at the press conference to promote the new movie in his home city yesterday (29.10.14), the 81-year-old star was asked what he does for the environment, to which he responded: "I was so poor for so long that I didn't use anything. I didn't eat very much, but I figured the world owed me a debt.
"I've been eating very well and have had a big car for a long time. But I still haven't caught up with my youth."
As well as not being worried about his carbon footprint, Michael recently revealed isn't too bothered about getting drunk anymore because he is too much of a "control freak" to enjoy the experience.
He said: "I'm a control freak. That's why I never get drunk. I've been drunk, but that was before I knew I was a control freak. I suppose it's just me, it's who I am. I love to be outside and I love to be casting an eye over everything."

Katie Price regrets not realising her friend Jane Pountney was having an affair with her husband.
The 36-year-old star is annoyed that she didn't immediately suspect her good pal was sleeping with her husband Kieran Hayler because the former model insists she had noticed Jane had changed her look somewhat and became suspicious as a result.
Katie - who has two children with Kieran, Bunny, two months, and 14-month-old Jett - said: "My only regret from the past year and a half is I knew Jane had changed and I knew she fancied Kieran.
"Why didn't I say something? Instead of saying how great she looked and all of that, I wish I'd clocked it before."
Katie took to Twitter earlier this year to threaten to divorce Kieran after revealing he had cheated on her with Jane, but the couple are set to renew their vows later this year and the reality TV star admits the ceremony will be particularly important to the plasterer following his infidelity.
When asked if it is important to her to take her vows again, Katie - who also has children Harvey, 12, from her past relationship with Dwight Yorke and Junior, nine, and Princess, seven, from her marriage to Peter Andre - added to Now magazine: "It's more important to Kieran.
"He wants to say those vows, look me in the eye and keep them."

Christopher Nolan was inspired to make films after watching '2001: A Space Odyssey' at the age of seven.
The filmmaker, who's become among the most influential people on the Hollywood scene over the last decade, revealed that his passion for cinema can be traced to his childhood, when he would watch the latest blockbusters in London.
Nolan - whose new sci-fi film 'Interstellar' features Anne Hathaway, Sir Michael Caine and Matthew Matthew McConaughey - remarked: "For me, the great thing about movies has always been the large screen, large audience experience. That's what you always hope for. One of my earliest movie-going memories was going to Leicester Square in London to see '2001' when I was seven years old and I've never forgotten the scale of that experience."
Speaking in promotion of his latest film, the 44-year-old director insisted he makes films on the scale of 'Interstellar' because it's what he loves, rather than because it's what the film studios demand.
He added: "I first saw an IMAX film when I was 15 and immediately wanted to make features at that point. So really, for me, working on this scale is just a long-held dream."

Jimmy Page feels "blessed" to still have "good" hearing despite years of being blasted by loud music in Led Zeppelin.
The 70-year-old guitarist has not been afflicted with hearing issues, such as tinnitus, like many of his rock 'n' roll peers even though he was constantly blasted by the late John Bonham's drums while on stage.
He revealed: "My hearing is actually really good, considering that searing top coming at me from those cymbals. As I'm advancing in years, a lot of my friends realise how good my hearing is. I'm really blessed. Without good hearing, you're f***ed in this business - especially on the details of this stuff, the subtlety of what I'm working on. I'm lucky with that."
Page insists he had to stand directly in front of Bonham when the group first started touring because it was the only way he could hear what the drummer and bass player John Paul Jones were playing.
Speaking to Rolling Stone magazine, he explained: "That was the best point for us to listen to each other. John Bonham always had his monitors really loud behind his kit. That was a good point to hear everything that was going out to the crowd. As stage monitors improved, we moved around more. But it was better to position yourself where you could hear the bass and vocals, to feel the drums and the urgency of the music. It was all listening."
Led Zeppelin - which also had Robert Plant on vocals - split in the wake of Bonham's alcohol-related death in October 1980, and Page insists it was never seriously considered to carry on without him.
He said: "Led Zeppelin wasn't a corporate entity. Led Zeppelin was an affair of the heart. Each of the members was important to the sum total of what we were. I like to think that if it had been me that wasn't there, the others would have made the same decision. And what were we going to do? Create a role for somebody, say, 'You have to do this, this way?' That wouldn't be honest."
Led Zeppelin last performed together in 2007 at a tribute concert for Ahmet Ertegün - the music executive who signed them to Atlantic Records - which feature John's son Jason Bonham on drums.

Taylor Swift's cat has turned into a diva.
The 'Shake It Off' hitmaker claims her three-year-old Scottish Fold Meredith Grey's personality has "changed" since she was voted the most popular celebrity cat of 2013.
The 24-year-old star told 'The View': "The first one Meredith started out as a very friendly kitten and then she became some sort of an Internet celebrity and I think she kind of changed a little.
"She just kind sits around and she's always giving me the side glance. Like I don't matter anymore to her because she knows that she was like 2013's most popular celebrity cat."
The blonde beauty says her other kitten, Olivia Benson, is very affectionate, but clumsy.
She said: "So then there's the new one who has terrible balance and walks into walls. Falls asleep on you purring, so she's like polar opposite."
Taylor, who is currently single, previously admitted she worries about being branded a "crazy cat lady" by potential boyfriends.
She said: "I asked around: I was like, 'Does two cats count as cats?' But then I thought, what imaginary guy's perspective am I thinking about this from? Someone is going to think I'm undateable for a lot of reasons before they think I'm undateable because I have two cats."

Nicole Kidman insists Keith Urban doesn't get jealous of her love scenes.
The 'Before I Go to Sleep' actress says her husband of eight years had no problem with her appearing naked in the new movie or shooting racy sex scenes with her co-star Colin Firth.
The 37-year-old star beauty told E! News: "[It was] a very quick, quick scene.
"I suppose I don't find those scenes awkward because once you're in character, you're in character. There is a way in which you work it out and if you're both actors then you know what you're doing. I mean, Keith's obviously easy with everything because he feels incredibly loved and protected. And I think once all of that is fine, then it's what we do."
The Australian actress, who has daughters, Sunday, six, and Faith, three, with the country singer, regrets recently admitting she hopes "every month I am pregnant but I'm not."
She said: "I've just got to learn. One, you can't be irreverent. Two, you've got to be very careful with humor. Three, you know. I never learn. I've been doing this so long..."
She added: "I mean, I would be blessed to have another child as...you know, we love our family. The chances of it are very slim, but hey, I'd be blessed."

Anne Hathaway "wasn't prepared" for her relationship to change after she got married.
The 'Interstellar' star, who tied the knot with Adam Shulman in September 2012, admits she fell more in love with him than ever after they exchanged vows.
The 31-year-old actress told the UK's The Daily Telegraph: "When we got married, I thought it was a great party. I honestly thought we were doing it more for tradition. I wasn't prepared for the radical shift my heart was going to have."
The brunette beauty is relieved the jewellery designer, 33, is able to travel with her a lot because he can take his work on the road.
She said: "I'm very fortunate that my husband has a job that allows him to travel and kind of make his own schedule. So he travels with me whenever possible. We have a rule that we aren't apart for more than two weeks."
The Oscar winner previously admitted she made the first move on Adam in 2008 after she discovered he was single.
She said: "I was in L.A. when I met him. I was told he had a girlfriend, and I backed off because I'm not that girl. Then when I found out six weeks later that he didn't have a girlfriend, I was like, 'We should throw a party. We should invite Adam.' "

Kourtney Kardashian admits her third pregnancy is taking "a toll" on her.
The 'Kourtney & Khloé Take The Hamptons' star, who already has son Mason, four, and daughter Penelope, two, with boyfriend Scott Disick, is set to give birth to another baby girl in December and says she is exhausted.
The 35-year-old beauty told UsMagazine.com: "I went to a wedding [of restaurateur Scott Sartiano and model Allie Rizzo] Saturday night (25.10.14), and then yesterday I was just so tired the whole day. Any little thing takes a toll on me."
She added: "I went to Disneyland for 10 hours... I usually go for at least 12, but that took like, two days [to recover]."
But Kourtney insists she loves being pregnant.
She said: "I feel good. I feel tired but in general, I do love being pregnant and always feel pretty good. I'm lucky. I always hear, like, horror stories."
The reality TV star's younger sister, Khloé Kardashian, thinks she has gained most of Kourtney's pregnancy weight.
She joked: "I gain her pregnancy weight... which sucks. In the Hamptons, I blamed her for everything. I would eat everything she ate. It was horrible."

Jennifer Aniston insists she only removed her engagement ring to get it cleaned.
The 45-year-old actress, who got engaged to 'The Leftovers' star Justin Theroux in August 2012, sparked rumours they had split after she was spotted out without her eight-carat radiant cut diamond sparkler in Los Angeles on Wednesday (29.10.14).
But a spokesperson for the 'Cake' beauty told E! News: "Everyone should calm down - the ring was just being cleaned and is safely back on her hand."
A source close to the couple recently revealed they are quietly planning to tie the knot in New York City in December.
The insider said: "It's really happening! Jen is excited beyond belief. She says it will be the best day of her life."
Justin, 43, previously confessed he feels a lot of pressure from the public to marry his fiancée, but isn't bothered by it.
He said: "There is this hum of pressure that - I can't stress enough - I just don't pay any attention to ... We're just doing our own thing. We are completely happy, obviously, but we're not on anyone else's timeframe."

Ricki Lake has split from Christian Evans.
The talk show host, who married the jewellery designer in April 2012, reportedly filed for divorce from him on October 16, citing irreconcilable differences.
According to court documents, obtained by gossip website TMZ.com, the 46-year-old star says they legally separated on October 9 and she is requesting to pay her estranged husband spousal support.
The duo are also rumoured to have a prenuptial agreement that includes details of how they will divide their property.
Ricki, who divorced her first husband, illustrator Rob Sussman, in 2005, with whom she has two children, Milo and Owen, previously credited Christian for helping her to be less cynical about love.
During an interview last year, she said: "For a long time I was involved in this very difficult marriage. I had all these struggles and a relationship filled with drama, which I thought was normal and healthy. But a marriage shouldn't be drama filled. It should be loving and based on a real partnership.
"It was very tough and traumatic and my children were very young. I was married for almost 10 years and I honestly did not think that I would ever get married again. I thought, 'I don't need a man. I am an independent woman. I am strong. I was very cynical about marriage but then I met this amazing person and he changed my perspective on what a partnership should be and the value of sharing your life with someone."

Harry Styles thinks "it's worrying" his vomit is being sold on eBay.
The 'Steal My Girl' hitmaker was surprised when fans erected a heartfelt shrine on the side of a busy Los Angeles freeway after he was recently forced to pull over and throw up there following a night of heavy partying with Lily Allen, and admits he doesn't know if anyone has purchased the item yet.
Speaking to Scott Mills on BBC Radio 1 today (29.10.14), the 20-year-old singer said: "It's worrying this is the world we live in."
Explaining what caused him to puke, he added: "I'd been on a hike. I'd been on a very long hike.
"It was about three weeks ago, so I'm fine now."
His One Direction bandmate Liam Payne added: "Woah, I saw that thing [the eBay listing], it's weird."
But the 21-year-old has his own issues to deal with, as he gets cabin fever from not being allowed to leave hotels for security reasons.
He said: "I just can't be kept inside for that long, it's just not fair. I can't deal with it. I've always been quite an outdoorsy type of person. I'm an adventurer, I like to explore."
Meanwhile, the British boyband - also comprised of Louis Tomlinson, Zayn Malik and Niall Horan - aren't worried about their private photographs ever being leaked online, as they don't use iCloud because Harry thinks "it's not a very complicated hack."
The group are gearing up to release their new album, 'Four,' next month, but haven't listened to the entire record together yet.
Zayn said: "I don't think we've quite listened to it together. We should do that."
The band are thrilled Danny DeVito agreed to appear in their latest music video.
Niall said: "He's Hollywood royalty to us, so for him to even want to be in our video was insane. It was a really good day."
