Selena Gomez Betrays ‘Mentor’ Jen With Justin

Selena Gomez was once mentored by Jennifer Aniston — but that isn't keeping her from hanging out with Justin Theroux even as the "Friends" star's divorce turns bitter!

The National ENQUIRER caught the troubled pop diva enjoying a star-studded Sunday with Justin and his pal Paul Rudd on May 6. Justin's frequent date Petra Collins were also along. Things aren't serious between Jennifer's ex and the artsy photographer, though — with Justin also recently out with 26-year-old model Erika Cardenas.

Justin, 46, also reportedly doesn't mind the age gap between him and 25-year-old Selena. Insiders told The ENQUIRER that Jennifer was furious over her fiancé flirting with Selena just before their short-lived marriage — blasting Justin for having a "creepy old-man" crush on her protégé!

The relationship between Jennifer and Selena got strained after a party at the 2015 Academy Awards, with Justin taking Selena out to the dance floor. "Jen thought Justin was making a fool out of himself by hanging on a girl young enough to be his daughter," said a spywitness.

The insider added that a "mortified" Jennifer was furious as Justin "was breakdancing and flailing all over the floor, trying to impress Selena." The incident seemed to end up as a tragic foreshadowing of Justin and Jen's short-lived marriage, which sources revealed was riddled with trust issues.

People also noticed that Justin's post-split return to social media featured him posing with puppies and giving a shout-out to Selena. RADAR Online recently reported that Justin and Selena have been texting, as well. And while Selena and Jennifer both recently attended the WE Day event on April 19, it was also the rare event where the two stars didn't pose together for photos!
