Rosi Sexton, one of the top female fighters in the world, has signed an exclusive contract with Bellator, the organization announced Thursday. Terms of the deal were not immediately disclosed, and it is unknown whether the 32-year-old will compete in one of the promotion's upcoming tournaments.

Bellator also announced Thursday that it will stage a 115-pound women's tournament during its third season, which kicks off Aug. 12. Sexton has competed at 125 and 115 pounds, so it is possible that she will be a part of that tournament.

MMA Fighting contacted Bellator to learn more about whether Sexton will be a part of the 115-pound tournament, but did not hear back from the organization.

Bellator is making a serious push to become the No. 1 destination in North America for the top female mixed martial artists. Earlier this month, the organization announced that it had signed Megumi Fujii, widely regarded as the best female fighter in the world, to a contract. With Fuji, and perhaps Sexton involved, the 115-pound tournament could easily become must-see television for female MMA fans.

Fujii is scheduled to make her Bellator debut June 10 against a yet-to-be announced opponent.

Sexton, 10-1, made her Bellator debut last June, defeating Valerie Coolbaugh via submission. She has not competed since then. Her only loss came against Gina Carano in September 2006.

Sexton holds wins over notable female fighters Debi Purcell and Carina Damm. She also has mathematics degree from Cambridge University and a PhD in theoretical computer science from Manchester.

Below is an interesting interview conducted last year with Sexton on a British TV show, GMTV.
