One Direction, Rihanna, Drake Celebrate Miami Heat's NBA Championship

Justin Bieber, Rick Ross and more also toast another championship for LeBron James and Co.

The Miami Heat wrapped up their third NBA Championship — and second of the LeBron/D-Wade/uh, Bosh "Big Three" era — on Thursday night, closing out the San Antonio Spurs in a grueling Game 7.

This was, of course, met with much jubilation by the Heat's celeb fans, who took to Twitter to revel in the team's victory. Others, like Drake, attempted to join the celebration in the Heat locker room, only to be turned away in spectacularly hilarious fashion (don't worry, Drizzy eventually ended up partying with LeBron and Dwyane until the wee hours of the morning).

Rihanna congratulated the Heat on Instagram, posting a pic of her mean-mugging in a LeBron James jersey (and Heat sunglasses), and writing to the two-time Finals MVP "I tried to tell 'em King! They didn't hear me doe! Shout out to you for giving us yet ANOTHER legit reason to talk that s---!" She also added several hashtags, including #HEAT, #KING, and, of course, #PhuckASpur.

Justin Bieber was actually at Game 7, though the on-court action apparently left him speechless, as all he could tweet was "Great game." Meanwhile, One Directioner Niall Horan was much more verbose, posting a lengthy congratulatory tweet that read "Go Heat! Lebron James is a monster! Talk about stepping up to the mark under pressure," and posting an adorable Instagram pic of him decked out in Heat gear.

Of course, there were a whole lot of Miami residents rejoicing, too, including Rick Ross (very demurely), DJ Khaled, who went ALL CAPS, Flo Rida's manager, Lee "Freezy" Prince — who loves the Heat so much he was willing to fight about it — and, of course, unofficial Miami ambassador Pitbull, who was ready to party.

Ed Sheeran was watching Game 7, too, though, he obviously didn't grasp the gravity of the situation, tweeting "I'm watching a basketball game, I haven't a clue what's going on." Meanwhile, noted Heat antagonizer Lil Wayne has refrained from weighing in on the team's championship, instead using Twitter to send a happy birthday message to his "lil homie Cameron."
