What can't Ronda Rousey do?

The UFC women's bantamweight champion joined ESPN's Lindsay Czarniak as the co-host of the 6 p.m. ET edition of "SportsCenter" on Wednesday.

"#RouseyCenter" featured some hard-hitting questions, tears and poor Tim Kurkjian getting put in an armbar.

After the show was over, Rousey had this message for the viewers:

That looks like a lot more fun than dealing with Justin Bieber, who apparently blew off Rousey and her 16-year-old sister at the annual Cannes Film Festival.

Apparently Rousey can't get a photo with Bieber, but she still makes for one heck of a good "SportsCenter" co-host.
