Selena Gomez  stepped out with Kendall and Kylie Jenner on Friday, taking their friendship to LA hot spot 1 Oak. The trio all donned black to celebrate Christian Combs's 16th birthday with a blowout bash. Christian's dad, Diddy , spared no expense for his boy's milestone. In a video he shared on Instagram, Christian takes the mic as two floors of partygoers dance along. The Jenner sisters weren't without supervision, though: Khloé Kardashian, who occasionally takes on the role of chaperone on E!'s Keeping Up With the Kardashians, also got in on the fun.
In typical fashion, the ladies captured the night in Instagram snaps, including what appears to be an afterparty moment Selena shared with Kylie. Selena captioned a photo showing the duo surrounded by flowers, "kylie&roses." Their big night comes nearly two weeks after Selena and Kendall's lunch date.  The friends spent some time apart as the Kardashian-Jenner family embarked on a bikini-filled vacation  in Thailand. Meanwhile, Selena took the stage at the Nickelodeon Kids' Choice Awards  to accept her favorite female singer trophy.
