UFC has become so popular that it's not only the fighters becoming more mainstream, it's the ring girls.

Arianny Celeste, probably the most famous ring girl in the world, is the cover model for November's Playboy magazine -- which comes out Friday -- and is featured in an 8-page spread.

Born in Las Vegas, the 24-year-old Celeste of Mexican and Filipino descent debuted in 2006 as an Octagon girl and has modeled for magazines such as Sports Illustrated, FHM and Maxim.
