"Had my UFC ring girl fitting today! Outfit looks bad ass!"

-- Holly Madison -- who is perhaps best known as Hugh Hefner's favorite girlfriend during "The Girls Next Door" -- Tweets about her fitting today for a UFC ring card girl get up. Madison has appeared in a UFC 98 video blog with company president Dana White not too long ago -- she's apparently a big fan of the sport. So is the 29-year-old Oregonian just having fun, getting dolled up for a special saunter at UFC 100 or will she somehow be included in the the first-ever Maxim UFC Octagon Girl Search at the fan expo ... or all of the above? Can't wait to get to the bottom of this ...
