Nobody knows more about what it feels like to be a woman spurned than Jennifer Aniston.
But now that she’s hooked up with actor/writer Justin Theroux, the actress runs the risk of being seen in a different light with rumors that Theroux left his girlfriend of 14 years Heidi Bivens to be with her.
But the costume designer’s mom, Marilyn Bivens, has exclusively told RadarOnline.com that her daughter is “doing fine” despite her high profile and painful split.
She said: “Heidi is doing fine and just trying to get on with her life.”
According to reports Theroux, 39, and Aniston, 42, first hooked-up last autumn while they had been filming Wanderlust together; he was last photographed in public with Bivens at The House Of Blues Leaves opening night on Broadway on April 25, 2011.
Aniston and her new man went public with a very public display of affection at the MTV Movie Awards bash last month at West Hollywood’s SoHo House.
Bivens has refused to talk about the split, but has now moved out of Theroux’s New York home; they first met when she was 20-years-old and he was 24.
Aniston was previously married to Brad Pitt, who famously dumped her after he hooked up with his Mr. and Mrs. Smith co-star Angelina Jolie.
Pitt walked out on his 5-year marriage to Aniston to be with Jolie in 2005. The couple are still together and now have six kids; Maddox, Pax, Zahara, Shiloh, plus twins Knox and Vivienne.
