The moment we learned Justin Bieber and Kendall Jenner had a hot date in Paris, we knew there was trouble in paradise for Jelena. Even though a good percentage of our readers believe that the Biebs and Kendall are just friends, apparently Selena Gomez doesn't, as she flew home from France alone last night, posted a very emo tweet AND unfollowed Bieber on Instagram!

After touching down at Los Angeles International Airport, Selena tweeted, "Random, long flight. So happy to be home," and added:
    "Sometimes we think we aren't good enough. But then I realize when I think I'm alone I have God."

On Tuesday Bieber took Kendall to dinner at Ferdi restaurant in Paris, and though Selena was also in the City of Light for Fashion Week, they two weren't seen together at all. The had just come from a romantic vacation in St. Martin, so something must have happened while the pop superstars were en route to Europe.

Bieber and Gomez both attended the CR Fashion Book Issue No. 5 launch party hosted by Carine Roitfeld, but the duo didn't pose for any pics together. Instead, Biebs cheesed it up for the cameras with Kendall and Gigi Hadid!

Earlier this year Selena had a blow-up with the Jenner sisters after Kylie was reportedly busted for sending Justin naked pictures, and Selena famously unfollowed both of the girls following the spat. It seems like Bieber has been hanging with Kendall to piss off Selena -- and it definitely worked! But will they get back together?
