“It was kind of an open secret that Justin was sweet on Selena when he and Jen hung out with her,” a source revealed.
Added the insider: “To be fair they did get on well but he’s asking for major trouble by trying to hang out with her so soon after his and Jen’s split.”
But Gomez, 25, is “not the type to blow someone off who she genuinely likes,” so she’s been going along with this and texting him right back.
The snitch insists it’s going to infuriate Aniston, 49, who saw the pop tart as “very much her friend not Justin’s.”
This isn’t the first time Theroux, 46, was canoodling with young Hollywood starlets soon after his split with Aniston.
He was spotted getting cozy with Emma Stone following the divorce bombshell.
According to various sources, the two had been leading separate lives for months, and often disagreed on basic things such as where to live and whether or not to start a family.
Theroux’s alleged wandering eye didn’t help either. In 2017, the actor reportedly got a bit too close to blonde beauty Naomi Watts, and Aniston was beyond “upset!”
