Brittney Palmer 2013 Calendar Shoot Upstaged by Arianny Celeste's Sexy Behind-the-Scenes Video?

Brittney Palmer, the legendary UFC ring girl and Playboy cover girl, will be releasing her very own hot and steamy calendar for 2013. While photos of Palmer's highly-anticipated calendar photo shoot were recently leaked on the web (Palmer groupies can thank Cage Potato for that), another famous UFC Octagon girl, Arianny Celeste, also plans on releasing a scantily-clad 2013 calendar. While Palmer has already released a mini behind-the-scenes video, looks like 26-year-old Celeste wants a part of the fun too, having recently leaked a sexy and revealing behind-the-scenes video of her own.

Fans can be the judge - which new UFC ring-turned-calendar girl will have the most success in 2013? Check out a collection of Palmer bikini-clad pics here, which will be featured in the upcoming calendar. And below is a short video clip of Palmer's calendar shoot, along with the 1:24 minute-long behind-the-scenes video of Celeste's shoot. This battle's a tough one... wonder if the ladies will decide to take it to the ring?
