Since her split from Justin Theroux, Jennifer Aniston has been leaning on her friends. Turns out Justin, 46, has been leaning on her friends, too! He’s been hanging out with her pal Emma Stone, 29, a lot lately, dining with her in NYC, vacationing with her at the Hotel du Cap Eden Roc in France in late May and grabbing dinner with her at Jennifer Lawrence’s place in NYC on June 11.

Now an insider says he’s planning to move in with Emma — whose home is not far from where the former Friends star lives in Bel Air. "Jen’s worst nightmare is about to come true," the insider exclusively told Life & Style. Though Justin considers NYC his home, "He’s told friends he’s moving to LA for a while, and it looks like he’ll be staying at Emma’s house. It’s the ultimate girl-code betrayal. Poor Jen just can’t seem to catch a break."

Things are heating up so much between Justin and Emma, "They could definitely become Hollywood’s next power couple," the insider says. "It would be so embarrassing for Jen if she starts having to avoid Justin and Emma at events and on red carpets, like she did with Brad Pitt and Angelina Jolie."
