This week's biggest Instagram event would have to be the reunion of YG and DJ Mustard. Before taking the stage together at Coachella, the two made an official announcement that they were back at it, writing, "For a whole year me and this nigga @djmustard ain't been BOOL "at all" But niggaz FINALLY sat it down and holla'D like some successful azz day 1's pose 2 & uhhhhhhh now.... WE BACK BITCHES!!!!".
Elsewhere, Post Malone put up a flex-worthy pic with Paris Hilton, Birdman took advantage of the hype around his Breakfast Club interview, Kehlani continued to show off her new blonde look, and Jennifer Lopez once again proved she's looking better than ever.
