A multiple time boxing champion, Holm easily won the first round by picking apart Rousey with her hands. Rousey's coach, Edmond Tarverdyan, said before the bout that he felt Rousey could outbox Holm, but that battle wasn't even close.

"I'm trying to take it all in, but it's crazy. I just had so much help with everything," Holm said before breaking into tears, reported Yahoo.com .

Twitter, obviously, went berserk:

Will there be a rematch? The stunning upset almost certainly sets up an instant rematch for Rousey, who broke into the mainstream in the last year bigger than any fighter in MMA history, according to MMAJunkie .
