UFC president Dana White dropped a bombshell Saturday night at UFC 158 by announcing the details for "The Ultimate Fighter 18."

UFC women's bantamweight champion Ronda Rousey will serve as one of the coaches for the FX series. The other coach will be determined by the winner of the Miesha Tate vs. Cat Zingano fight, which will be held at the TUF 17 Finale on April 13 at the Hard Rock Hotel and Casino in Las Vegas.

White also announced that the next season will feature both bantamweight men's and women's competitors.

This marks both the first time in TUF history that the show will feature women in either a fighting or coaching capacity. Rousey is coming off a first-round submission victory over Liz Carmouche at UFC 157 in the first women's fight in UFC history.

White also announced an open casting call for the show for April 15 in Las Vegas.
