With UFC bantamweight champ Ronda Rousey and bitter rival Miesha Tate (pictured) serving as opposing coaches on “The Ultimate Fighter 18,” this upcoming season of the long-running reality show is getting the breath of fresh air it desperately needs.

For obvious reasons, nobody has shared specifics about the drama that transpired between the archenemies during filming. However, UFC president Dana White, Rousey and now Tate have all said Rousey shows another side of herself that might not be too appealing.

Tate, who hosted a Google Hangout Friday with FoxSports.com, said Rousey “flipped” about a week after filming started. Also, the “Rowdy” one became quite the “b****” as filming wore on.

Tate challenges Rousey for her crown on New Year’s Eve weekend at UFC 168.

TUF 18 premieres September 4 on FOX Sports 1.
