ODELL BECKHAM JR. PARTIES IN MIAMI FOR SI SWIM WEEK ...with rumored girlfriend Hailey Baldwin's ex Justin Bieber and others 5/13/2019 10:30 AM PST

Odell Beckham Jr. had a fully lit night in Miami for Sports Illustrated Swim week, owning the stage at LIV Nightclub. Witnesses tell us he showed up at around 11 PM Thursday night ... flanked by some famous faces. He reportedly bought a table for a group of friends, which included teammates Baker Mayfield and Jarvis Landry, singers Trey Songz and ... on and off again best bud Justin Bieber. TMZ also learned SI models Camille Kostek, Barbara Palvin (Mayfield's newest fling), Jasmine Sanders and Kelsey Merritt were also seen popping bottles nearby. The Browns newest wide reciever, has been rumored to be dating model Hailey Baldwin who dated Bieber back in 2015. Sources say he's likely the reason the pair met. Hailey and Odell have been spotted on mutiple occasions together (Paris Fashion Week, Coachella and at the Met Gala last week) but neither will publicly confirm relationship. Bieber unfollowed the couple back in December, when the two were caught canoodling in Aspen over a candle lit dinner but refollowed Beckham after Fashion Week. Hmmmmmmmmmmmm ... Wonder how Hailey feels about this. Check out the vids from Trey's Instagram story ... you can see Beckham sing to Migos's "Bad and Boujee" and dance to Young M.A's "OOOUUU" ... two classics. We're happy to see his trade to Cleveland doesn't have him down in the dumps anymore but let's hope his newly mended friendship doesn't cause any problems with his girlfriend.
