UFC welterweight champion Georges St. Pierre will have plenty to say about the UFC 143 main event when he participates in a live chat with MMAFighting.com readers on Friday.

The winner of that main event, Nick Diaz vs. Carlos Condit, will earn the interim welterweight title, and our live chat is your chance to ask St. Pierre who he thinks will win, who he'd rather fight, how his rehabilitation from knee surgery is going and anything else you'd like to know.

The chat begins at 4 PM ET below.
