Machine Gun Kelly
Try to photobomb the tattooed, mohawk-sporting MGK, who popped up in Haden's picture during the Eastern Conference Finals and tweeted it out with the caption "meme it." Throw up an "L" for "Lace Up," if you're able to get close by. Pay him back by asking the Twittersphere for a caption.
Floyd Mayweather: You'll know it's Mayweather, because he'll be the guy courtside dressed head-to-toe in the Money Team gear and wearing ridiculous sunglasses inside. And don't mock him for wearing jorts. He is, after all, Floyd Mayweather.
Jay Z and Beyonce: It's still unclear if the power pair was really spotted in the Euclid Avenue Starbucks during the Cavs opener, but it’s a long shot (C'mon guys do you really think Queen Bey gets her own coffee?). You’ll score points if you support her vegan announcement by offering her a Restore Cold Pressed juice (Cavs player Matthew Dellavedova was spotted at the new downtown shop).
Kanye West: Sneak down to the court and wish Yeezy a happy belated birthday. Try to get him to smile. He's really, really good at avoiding smiling while on camera.
Shaq: Ask Shaq which club he plans on going to after the game so you can try to re-create his photo with MGK while 'Till I Die' and "Till I Die Part II" play on loop. Don't forget to ask him about the 'Shaqtus' cake Colossal Cupcakes made him.
Rihanna: You can try to cheer as loud as RiRi, but the bar is set high. The singer attended both games in Oakland to cheer on LeBron and was asked to move seats after her cheering annoyed Warriors co-owner Joe Lacob during Game 1. Maybe this time she'll be seated by Cavs owner Dan Gilbert.
JoAnna Garcia Swisher: You're more likely to find the actress down the street at Progressive Field, as her husband Nick Swisher and the Cleveland Indians play the Seattle Mariners tonight. But if you do happen to see her, she'll might be screaming loudly for Matthew Dellavedova and freaking out just as much as your average fan in the crowd. Except for the fact that she's an Astronaut Wife.
Rascal Flatts: Gary LeVox, the lead singer vocalist in Rascal Flatts, is from Westerville, Ohio, and has worked with Bieber in the past. So after he and the rest of Rascal Flatts perform the national anthem, look to the Bieber-Usher area.
Johnny Manziel: Regardless of your post-Browns season emotions toward Johnny Football, do not, under any circumstances, antagonize Manziel. He may throw a water bottle at you. He'll probably be with teammate and friend Haden courtside or he may even head back to his old stomping grounds at The 9 for an afterparty at the Vault Social Lounge. Oh wait, we forgot he dropped his party boy lifestyle for a quiet existence in a golf course community.
