If you weren't sure whether or not to believe the Jelena reunion rumors before, things just got a lot more interesting! Justin's drag racing pal Khalil posted a video of the on-and-off couple hanging out at Alfredo Flores' beach birthday party in Malibu last night.
It's hard to see much in the clip, but that's definitely Justin and Selena in the background! According to TMZ, Sel spent the entire day at the beach riding around with her ex on his Can-Am Spyder 3-wheeler!
Can you believe that Jelena is really hanging out again? Do you think that they're dating or just good friends? Tell us in the comments!
