Mike Mizanin – a former reality star from “Real World: Season 10” — was officially crowned as the heavyweight champion of the WWE last night … after a huge surprise upset victory over Randy Orton.

“The Miz” — who came up with his own nickname during the MTV show back in 2001 — began wrestling with the WWE back in 2004.

Miz ain’t the only ex-Real Worlder having a huge year — Sean Duffy from Season 6 won a seat in Congress earlier this month.

Maybe there’s still hope for Puck …
