Rumours: Jennifer Aniston has been accused of stealing new man Justin Theroux (pictured together with Jason Sudeikis) 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.
Heartbroken: Costume Designer Heidi Bivens says she only moved out of the couple's home last weekend after 14 years together
'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.'
