According to a Dec. 29 post from FOX Sports, UFC bantamweight title challenger Miesha Tate (13-5) walked out to Katy Perry's anthemic power pop tune, "Roar," for her UFC 168 fight against 135-pound champ Ronda Rousey (8-0).
Tate, 27, obviously picked the song because of its inspirational lyrics about having the "eye of a tiger" and the heart of a champion.
Unfortunately for Tate, it didn't do much to help her during the fight.
Rousey, 26, utilized her strong judo base to toss Tate around like a rag doll through much of the fight, before ultimately tapping her out with an armbar in the third frame.
Tate may have walked out to "Roar," but Rousey heard some roars of her own when she refused to shake her opponent's hand after the fight.
"I feel like the day that she formally apologizes to my coach Edmond (Tarverdyan) and Chris Beal and they accept that apology, then I will consider shaking your hand again," Rousey said at the UFC 168 post fight press conference. "I said up there boos are not (more) important to me than my family. If I feel like you've done wrong against my family, you need to make that right before I can shake your hand. It means something to me, it's not something I just throw out there.
"She's a great fighter. It was an amazing fight she put out. She has my respect entirely in that regard, but she really needs to make up a few things she's done before I will shake her hand."
Rousey says she wasn't surprised when the crowd booed her.
"I wasn't surprised at all," Rousey explained. "I was aware of the role that I was in. This is the favorite analogy that I use — Batman played the bad guy and let Scarface (editor's note: Rousey likely means Two-Face) look like the good guy because that's what Gotham City needed at the time. So for every fight I approach it for what's needed at the time."
Following UFC 168, Rousey's longtime teammate and training partner, Marina Shafir, ripped into Tate for choosing a Katy Perry song as her walkout.
"Take notes people. That's what happens when walk out to Katy Perry," Shafir tweeted.
