Ashlee Simpson brought her fiancé to her ex-boyfriend's birthday bash.
The 29-year-old star, who got engaged to actor Evan Ross earlier this year, helped Ryan Cabrera celebrate his 32nd birthday at the Kia Motors Malibu Estate in California on Sunday (13.07.14).
An eyewitness, who saw the couple there, told UsMagazine.com: "They were both super cute with one another, very affectionate and very touchy feely.
"At one point Ashlee even had Evan sitting on her lap as they conversed with their friends."
The blonde beauty dated Ryan, who was previously managed by her father, Joe Simpson, in 2004.
The 'Pieces of Me' hitmaker was also overheard "urging Ryan to play his new record for Evan so he could listen to it and maybe give him some insight on some lyrics that Ryan was struggling with. Evan and Ryan talked about collaborating and getting in the studio together. Both of them sounded super stoked on the idea and will be making it happen sooner than later."
Ashlee, who has five-year-old son Bronx with ex-husband Pete Wentz, will reportedly marry Evan, 25, at his mother Diana Ross' mansion in Los Angeles next month.

Wentworth Miller felt he was "feeding a fantasy" before announcing he is gay.
The former 'Prison Break' star, who opened up about his sexuality for the first time last August, says he has a better relationship with his fans now.
The 42-year-old actor told Details magazine: "I feel more fully expressed.
"After 'Prison Break,' I came to grips with the fact that my public persona was in misalignment with how I actually felt. I was out to a handful of people in my twenties, and once I hit 30, I was out to family and friends. But professionally, I was feeding a fantasy. I created this air of 'We don't address that thing.' "
Asked if he felt like he was lying about his sexuality in the past, he said: "My face was on billboards, and I thought it was my job to act a certain way. But I think audiences knew to a certain degree.
"The people onscreen aren't the characters they're playing. They're our projection of who we want them to be. I think it's possible to have a man-crush if you're not gay or to have a crush on a guy you know to be gay if you're a woman."
He added: "Attraction is fluid, and I think our imaginations are strong enough to hold a container for all of this complexity, even if we know on a subconscious level something's not what it appears to be."

Blake Lively thinks Ryan Reynolds is going to be a great father.
The 26-year-old actress, who married her 'The Green Lantern' co-star, 37, in a secret ceremony in September 2012, admits she loves the fact he is more than a decade older than her because he "lived so much" before they got together.
The former 'Gossip Girl' star said: "He's going to be a great father and leader and patriarch - he's so meant to be all of those things. The fact that he lived so much before we got together, he's the exact realised person that he should be. And so I get to share my life with the person he's become, and we get to grow from there."
The blonde beauty claims their wedding "was becoming a disaster" before they asked Martha Stewart to oversee the event in South Carolina.
The 'Age of Adaline' star also told the August issue of Vogue magazine that she and Ryan, who was previously married to Scarlett Johansson, collaborate on everything, including her new lifestyle website, Preserve.
She said: "He's a part of it because everything we do in life we do together. If I'm working on a movie, he helps me with my character; I do the same with him. Picking out a coffee table. What we're going to eat. He's a beautiful writer - he's written a lot of stuff for us. And he's got a great barometer and he knows me, so he will tell me if it's not as good as it can be."
Her new venture has already been compared to Gwyneth Paltrow's website Goop and Blake admits she is inspired by the actress.
She said: "I'm always the first person to defend Gwyneth Paltrow. Or any woman in a position of power, like Martha Stewart or Oprah, who gets burned because they have paved the path for so many other women who are doing something they believe in."

Christina Milian's new romance with Lil Wayne is reportedly a publicity stunt.
The 'Dip It Low' hitmaker, who recently ended her engagement with Jas Prince, was spotted holding hands with the rapper at the ESPY Awards in Los Angles last night (17.07.14), sparking rumours they're dating.
A source told gossip website TMZ.com that they are definitely not in a relationship and they are merely attempting to generate publicity, as Christina recently signed a deal with his record label, Young Money Entertainment.
But another source told UsMagazine.com: "It is totally true. They are hooking up."
The duo have been friends for a number of years, as Christina has four-year-old daughter Violet with ex-husband The Dream, while Lil Wayne's ex-girlfriend Nivea also has three children with The Dream.
The 32-year-old singer moved out of the house she shared with Jas, the CEO of Rap-A-Lot-Records, last month and hinted she was ready to move on.
She wrote on Instagram: "There comes a time in life, when you walk away from all the drama and people who create it. Surround yourself with people who make you laugh, forget the bad, and focus on the good. Love the people who treat you right. Pray for the ones who don't. Life is too short to be anything but happy. Falling down is part of life, getting back up is living."

Adam Levine will reportedly marry Behati Prinsloo in Mexico tomorrow (19.07.14).
The Maroon 5 frontman, who got engaged last July, is expected to exchange vows with the Namibian model in an intimate beach ceremony at the exclusive Hotel El Ganzo in Los Cabos.
A source told the MailOnline that the 35-year-old singer and his 25-year-old fiancée checked into the resort today (18.07.14) ahead of their nuptials.
They are believed to have booked out all 72-rooms for their guests, including 'The Wolf of Wall Street' star Jonah Hill, who has known the singer since childhood and whose older brother, Jordan Feldstein, manages Adam's band.
Behati's close friends and Victoria's Secret colleagues Candice Swanepoel and Erin Heatherton are also expected to attend the festivities, including the couple's rehearsal dinner tonight.
The 'Voice' USA mentor recently admitted he feels ready to settle down after dating a string of beauties, including model Anne V, in the past.
He said: "In my lifetime I've done it right. I've had plenty of fun."
He added: "I definitely feel like I'm sitting in the chair I'm supposed to be sitting in right now. It all feels very natural."

David Beckham admits he is a strict father.
The 39-year-old retired soccer star - who has sons Brooklyn, 15, Romeo, 11, and Cruz, nine, and three-year-old daughter Harper with wife Victoria Beckham - only lets their sons play video games for one hour a day, as he prefers them to play outside.
Asked if his children play sports-themed video games, he told PEOPLE.com at the inaugural Nickelodeon Kids' Choice Sports Awards in Los Angeles last night (17.07.14): "We put a time limit on it. You have to. No more than an hour. I know that sounds pretty harsh, but I want my boys to be outside playing."
He added: "It's so important to me that they're involved in sports -- for discipline and health. [Brooklyn] is pretty skilful. My middle one, Romeo, is the quick one; he's super fast. The small one, [Cruz], is the tough one, of course -- being the smallest boy."
But David says his daughter is more interested in watching movies.
He said: "She just had her third birthday party and it was 'Frozen'-themed. My little girl is the biggest 'Frozen' fan ever."

Harry Styles was among the stars at Warner Music Group's big summer party last night (17.07.14).
The 20-year-old heartthrob took a break from One Direction's sell-out 'Where We Are' stadium world tour to sip cocktails at the lavish party, held in association with British GQ magazine, at Shoreditch House in trendy east London.
Harry and other A-list guests enjoyed music-themed cocktails including the Parlophone Punch, Atlantic Breeze and Warner Spritz.
Other stars who attended the lavish bash included former Girls Aloud star Nicola Roberts, who wore a striking halter-neck red dress, Conor Maynard, Rudimental and Amber Le Bon.
Harry was recently praised for his songwriting skills by US songbird Ariana Grande, for whom he penned a track called 'A Little Bit of Your Heart'.
She said: "I was at the studio one day and he was there, and literally, [songwriters] Johan [Carlsson] and Savan [Kotecha] were like, 'Hey, do you want to write something for Ariana?' And he was like, 'Sure, mate.' And he just did.
"It's a beautiful song. He's an amazing writer. It's really beautiful. He's amazingly talented."

Nina Dobrev tries to be good to everyone including her exes.
The 25-year-old actress likes to be positive and treat people well even if she has been through a bitter break-up with them.
She told Nylon magazine: "I don't like any kind of negativity.
"I try to be good to everyone, whether it's a love, a friend, an ex. I'll always try to treat people the way I want to be treated."
Nina's 'Vampire Diaries' co-star and ex-boyfriend Ian Somerhalder agrees that she's good at practicing what she preaches.
He joked: "She always lets me have the last fry."
The actress' love life is never without speculation and she has recently been linked to fellow actor James Marsden after the pair were spotted kissing "in a corner" at a karaoke bar in New Orleans.
A source told the American edition of OK! magazine: "[There was] more kissing than singing."
The stars reportedly left the bar together at 3am, before jumping in a taxi and passionately locking lips again.
A source told HollywoodLife.com: "Nina thinks James is hot. They have met before and they did hook up and had a great time. It was a fun night of drinking and hooking up on Bourbon Street."

Cher Lloyd has defended Cheryl Cole's choice to marry her boyfriend of three months.
The 'Crazy Stupid Love' singer wed her French beau Jean-Bernard Fernandez-Versini in a private ceremony on the Caribbean island of Mustique earlier this month and Cher - who married long-term boyfriend Craig Monk last year - believes thinks it's "amazing" her former 'X Factor' mentor has found love again.
Speaking on Birmingham's Free Radio, Cher said: "I'm really happy for her. There is no reason for anyone not to be happy for her. I have been looking at Twitter a lot and a lot of people are saying, 'Oh, three months this and three months that.'
"You can't put a time on anything and people should realise you only have one life and you don't know what is going to happen to you.
"So I feel that it's amazing for her to be able to do that, and fingers crossed she has little babies. She is going to have beautiful children."
The 20-year-old singer also offered Cheryl, 31, marital advice, cautioning the singer to "pick her battles" with Jean-Bernard.
She said: "One of the things I have learned is pick your battles. If he's left a wet towel on the bed, pick it up and remove it yourself. There is no point going over the same thing again and again, because he won't listen. He will not remember to not put a wet towel on the bed.
"But then in other situations where he's really hacked you off, that's your battle that you pick. That's something that I do."

David Beckham's kids branded him "super old" when he told them about his Legend Award.
The 39-year-old retired soccer star - who has sons Brooklyn, 15, Romeo, 11, and Cruz, nine, and two-year-old daughter Harper with Victoria Beckham - was bestowed with the accolade at the first ever Nickelodeon Kids' Choice Sports Awards last night (17.07.14) but he admits news of his prize was met with a funny reaction from his offspring.
Quizzed about their response, he said: "Super amazing! One of them said [I was] super old, so that made me laugh today. But I like to think they think I am amazing."
David - who was covered in golden slime as he accepted his award - also expressed how much his new accolade means to him, especially as it's voted for by children.
He explained to 'Access Hollywood': "It means a lot because obviously I have come to the end of my career as a soccer player - a 22-year career - and at the end of your career it's nice to still receive awards, especially when it's from kids.
"When kids vote for you ... kids are very honest, I know that, I have four myself, so when you receive an award it means a lot."

Nick Cannon wants his children to become nuclear scientists.
The 'America's Got Talent' host - who is married to singer Mariah Carey - insists that he "never" wants his three-year-old twins, Moroccan and Monroe, to follow in their famous parents' footsteps and hopes they seek a more grounded profession.
He said: "I don't want my kids to be on TV, that's the only thing [I don't want them to do].
"I just want them to shoot for something else, because it's already in them - like, if you wanna act, be in the school choir. [And] if you wanna sing, be in the school choir.
"A nuclear scientist - can I get one of those? Can I get a heart surgeon in the family?"
Despite his feelings on TV, Nick remains a huge fan of popular reality show 'America's Got Talent', which he has been presenting over the summer.
Nick believes the programme is good "family fun" and that's why it has outlasted so many rival shows.
He told 'Access Hollywood': "To be able to turn on the television for two hours and just relax and have fun with your family, that's what it's all about."

Britain's Prince William has paid tribute to the victims of the Malaysian air crash.
The 31-year-old royal said his "thoughts and prayers" go out to the families of the 298 people killed in the tragic incident yesterday (17.07.14), which saw flight MH17 crash in Ukraine after taking off from Amsterdam.
Speaking during the unveiling of a statue to the first man to identify Australia as a continent, he said at Australia House in London today (18.07.14): "I know that I speak for all of us here when I acknowledge our deep sadness following yesterday's disaster in the Ukraine. For all of us who have lost fellow countrymen and women in the tragedy, words cannot do justice to our sense of loss."
The crash - which has killed at least six Britons - comes just four months after Malaysian Airlines flight MH370 disappeared en route from Kuala Lumpar to Beijing on March 4, with 239 people suspected to be dead.
The prince added: "The crash is a particularly cruel tragedy coming so soon after the loss of MH370.
"Please be assured of my family's thoughts and prayers at this time."
