It’s been 10 years (exactly!) since Mean Girls first hit theaters. But Selena Gomez’s very public feud with her former friends Kylie and Kendall Jenner reassures us the drama that dominated Girl World a decade ago is still alive and well.

Last week, the 21-year-old songstress made her issues with the sisters known after she unfollowed them on Instagram and deleted all evidence of their weekend at Coachella from her account—allegedly in an effort to eliminate the “toxic” sisters from her life.

However, a new report claims the real reason Selena severed her relationship with the teens has to do with her on-again-off-again boyfriend Justin Bieber.

Kendall and Kylie Blow Off Claims Selena Gomez Thinks They’re Toxic—Claiming She’s the Bad Influence!

According to an insider, the former Disney Channel actress lost her cool at the music festival after finding messages and pictures from Kylie on JB’s phone!

“Selena flipped out and there was a huge fight between the girls,” the insider tells Radar. “She now wants nothing to do with Kylie or Kendall.”

The insider adds Selena—who recently completed a stint in rehab—“was already getting bad vibes from Kylie,” and thought the 16-year-old was too much of a partier.

And she’s not the only one concerned with the teen’s reckless habits.

“They are both turning out to be wild – they love to party and hang out with Justin Bieber’s crew,” a source tells In Touch. “Kendall and Kylie like to have a good time. They’re headed for trouble.”

Radar’s source explains the Biebs didn’t exactly get off scot-free, either.

“Selena was also furious at Justin,” the insider says. “They’re not together right now.”

However, the Jenner girls and Justin have all made it clear they aren’t letting Selena’s feelings get in the way of their friendship.

Earlier this week, Kendall and the 20-year-old singer were spotted entering the same Queens, N.Y. studio—where they are rumored to be shooting a Calvin Klein ad together—before joining their pal Hailey Baldwin (Stephen Baldwin’s 18-year-old daughter) for dinner at Manhattan hotspot Nobu.
