Caitlin O'Connor is not just a pretty face with a voluptuous body. She is also a boxing fan and an avid supporter of the undefeated American boxer Floyd Mayweather Jr.

O'Connor, who graced the cover of Maxim and other men's magazine, attended a party hosted by former baseball player Jose Canseco last week in Los Angeles. During the event, the model hooked it up with ESNews reporter Elie Seckback to answer a few questions about boxing. And by everybody's surprise, O'Connor knows her boxing.

Seckbach asked O'Connor which boxer is she rooting for in the upcoming showdown between Floyd Mayweather Jr and Saul Canelo Alvarez.

O'Connor did not have second thought, believing Mayweather is going to win the match because she doesn't expect the American boxer to get knocked down.

"Gotta go with Floyd Mayweather," O'Connor said, "Because he's not gonna get knocked down, I already know."

O'Connor is set to appear as one of the vice girls for Maxim Magazine this July. In case you are interested to know better who she is, you can follow her at Caitlin_O'Connor on Twitter.

Here are some of the shots for Mayweather's lady.
