Rumours: Jennifer Aniston has been accused of stealing new man Justin Theroux from his long-time partner.
She won the sympathy of millions when she was dumped by then-husband Brad Pitt for Angelina Jolie.
But despite famously calling her love rival ‘uncool’ in an interview for stealing her man, Jennifer Aniston is now being branded a homewrecker herself.
The long-time partner of Jennifer’s rumoured new boyfriend Justin Theroux has revealed that she moved out of the couple’s home only last weekend.

Costume Designer Heidi Bivens is understood to be devastated over the new romance.
A spokesperson for Bivens told the NY Post: ‘Heidi and Justin have been together for 14 years.
‘They met when she was 20 years old and he 24, and yes, she just moved out of their home last weekend. She has no comment.’
Jennifer, 42, and Justin, 39, made their first public appearance last week at the MTV Movie Awards after party at the Soho House in Hollywood.

And according to People magazine, Jen threw a small get-together for her best friends including Chelsea Handler and Courteney Cox on May 27 to introduce them to Theroux.
A source told the magazine: ‘They all had a great time and enjoyed Justin’s company.’
Despite the claims, a friend of Your Highness star Theroux insists: ‘Things were already over between him and Heidi before he got close to Jen.’

The pair met on the set of movie Wanderlust last autumn.
Over the past eight weeks they have been spotted on dates at various Hollywood haunts, but avoided being photographed together until last week.
Grazia magazine claims that Jennifer has even given New York-based Justin the keys to her Beverly Hills home.
‘Justin has to be in LA all the time for business,’ a source told Grazia.
‘He usually stays in hotels, but Jen said he could start staying at her place.’
Despite being known as the poster girl for wronged women, this is actually not the first time Aniston has been accused of stealing another woman’s man.
Christopher and his wife Joanne finalised their divorce a month before he was spotted out with Jennifer.A year ago the Friends star was spotted on dates with True Blood actor Christopher Gartin, who had then recently split from one of Jennifer’s closest friends.
The Australian wedding planner told Radar Online at the time: ‘Jennifer has been my friend – our friend – for over 10 years… we have known each other a long time.’
A pal of Joanne added: ‘It’s been difficult for Joanne. It just seems so bizarre to me because Jo and Jen are such good friends.

‘I find it very strange that Jen would do that,’ she told Australian magazine Woman’s Day.
‘Jen is in their lives. She comes to their house and (their children) Sydney and Flynn go to her house a lot, to play in the pool.’
In a 2008 interview with Vogue magazine, Jennifer frankly told of her feelings towards Angelina Jolie’s remarks about falling in love with Brad Pitt on the set of Mr and Mrs Smith.
She said: ‘There was stuff printed there that was definitely from a time when I was unaware that it was happening.

‘I felt those details were a little inappropriate to discuss. That stuff about how she couldn’t wait to get to work every day? That was really uncool.’
Jennifer is currently starring as a sex-crazed dentist whose predatory behaviour leads her assistant to plot her murder in Horrible Bosses.
Representatives for both Theroux and Aniston are yet to respond to Mail Online’s request for comment.
