“Jen has been leaning hard on Gerard as her relationship with Justin continues to disintegrate!” a source close to the former Friends star told Radar.
The shocking revelation comes just weeks after the couple reportedly had an explosive fight at their Bel-Air mansion in December — with Theroux storming out and checking into a Beverly Hills hotel.
Immediately, pals confided, Aniston turned to Butler, 48, the rugged Scottish star she dated from 2009 to 2010.
“It seems like Jen has turned to Gerard to fill the void left by Justin,” said an insider.
Meanwhile, the handsome actor has shown no hesitation to express admiration for his ex!
While promoting his latest flick, Den of Thieves, on Watch What Happens Live with Andy Cohen in January, Butler happily rated Aniston as a much better kisser than his Lara Croft Tomb Raider: The Cradle of Life co-star, Angelina Jolie!
“It’s no coincidence that , Gerard made a public display of affection and loyalty toward her!” the source noted.
For her part, Aniston, 49, is thrilled with the attention.
“She’s really touched that Gerard is proving he has her back,” revealed the insider, who confided the pair have been flirting with a reunion for a while.
“Jen and Gerard reconnected a few months ago when she and Justin first started butting heads,” said the insider.
And though he’s been linked with actress Morgan Brown, pals revealed Butler feels he has unfinished business with Aniston.
“Gerard told Jen he’s still carrying a torch for her,” the source revealed.
“He’s made it clear that the timing wasn’t right before, but he’s ready to commit to her now.”
