Delivering a beating to “bad girl” Chael Sonnen would be a “great” way to end his career, according to Tito Ortiz.

On Thursday officials announced the signing of Sonnen, a former UFC title challenger who ended his retirement and a drug suspension to sign with Bellator.

During a media call on Friday, Sonnen (28-14-1 MMA, 0-0 BMMA), who’s recently competed at middleweight and light heavyweight, said he’s willing to fight anyone at about any weight – middleweight Rory MacDonald (18-4 MMA, 0-0 BMMA), light heavyweight Wanderlei Silva (35-12-1 MMA, 0-0 BMMA) and heavyweight Fedor Emelianenko (36-4 MMA, 0-0 BMMA), for example. He also made special mention of Ortiz (18-12-1 MMA, 2-1 BMMA).

“Tito, you know I could whip your ass,” Sonnen, 39, said. “And he gives me that exact same look. Every time we’re in the same room, it’s like this big alpha male contest. If the ‘Bad Boy’ wants a piece of the ‘Bad Guy,’ all he’s got to do is say my name.”

That apparently caught the attention of Ortiz, who fired back (via Twitter):

After retiring and leaving the UFC in 2012, Ortiz eventually signed with Bellator and revived his career to upset Alexander Shlemenko and defeat Stephan Bonnar in 2014. However, this past year the 41-year-old suffered a submission loss to light-heavyweight champion Liam McGeary and hasn’t fought since then.
