#2 Former WWE Champion Chris Jericho
Former AEW World Champion Chris Jericho (he's won a few other titles, too, I've been told) has been a consistently busy guy throughout the majority of his career. When he's not doing the wrestling thing, he's touring with his metal band Fozzy or he's writing another book. Well before USA hired WWE star The Miz to host the latest attempt at recreating Japanese gameshow - but well after WWE Hall of Famer Mick Foley hosted a show about robots fightin' - the ABC Network tapped the Ayatollah of Rock and Rolla to host their game show Downfall.
Although, instead of having contestants create memes involving Hitler, they decided to instead just throw prizes off the roofs of buildings.
No. Seriously.
He's also appeared on that same network's Dancing With The Stars show, which pairs professional dancers with celebrities (sometimes in the loosest sense of the word, but they're still celebrities.) Considering Jericho wasn't one of the professional dancers, it can only be concluded that WWE's Best There Is At What He Does is considered, by the ABC Network at least, to be a "star."
Although he's clearly not the best at dancing, as he didn't win.
He's also starred in his own webseries But, I'm Chris Jericho..., as well as Comedy Central's Nothing to Report. He even had a small role in Sharknado 3: Oh Hell No! although who hasn't been in one of those movies? I know WWE Hall of Famer Kurt Angle has.
