Kim Kardashian, Justin Bieber, Suni Lee Attend IShowSpeed’s Series Launch Party

Kim Kardashian, Justin Bieber and Suni Lee all hit an event on Tuesday … but no, it wasn’t for an awards show — it was all thanks to IShowSpeed!!

The streaming superstar hosted a night at the Los Angeles Memorial Coliseum … and a bunch of A-listers were present for the premiere of his six-episode YouTube series, “Speed Goes Pro.”

Some of the biggest celebrities rolled through in support … including Kim K, who chatted with Speed about his 35-day tour that wrapped up in L.A. She also brought some of her kids to meet him … earning her some major cool mom points.

JB also pulled up rockin’ furry shades and a hoodie … and jammed out to DJ TJ Mizell‘s tunes — even when his own track, “Speed Demon,” came on.

Speed was shocked to see Olympic medalist Suni Lee, who looked stunning in a red dress … but was super shy for his stream.

The guest list didn’t stop there … WWE Superstars Sheamus, Drew McIntyre and Randy Orton were also there — with Speed attempting to RKO the latter.

Remember, Orton did his signature move to Speed at WrestleMania 40.

FYI, “Speed Goes Pro” is a series where the athletic streamer goes head-to-head with some of the biggest sports stars … starting with Tom Brady in episode one.

He also trained with New York Jets star Sauce Gardner and Brady’s former teammate, Danny Amendola, in the vid … all in an attempt to intercept the seven-time Super Bowl champ.
