UFC Octagon Girl Arianny Celeste is taking her clothes off in celebration of tomorrow's "Hangover 3" movie release.

The wolf pack is back! And it has a new member...

That's right, mixed martial arts (MMA) fans, Ultimate Fighting Championship (UFC) Octagon Girl Arianny Celeste has returned with another round of "Strip Trivia" from CineFX, which means you take a short quiz and get rewarded with booty.

Not the full monty, mind you, but definitely a fair amount of skin.

Watch her tackle Star Trek here, Harry Potter here, Anchorman here, Iron Man here, and Simpsons here.

This week, Celeste will test you on specific parts of the hit movie "Hangover 3," which hits theaters tomorrow (May 23, 2013). I know, I know, you haven't seen it yet, but hopefully you saw parts one and two, which is where most of the questions come from anyway.

Guess the answer right and she removes an article of clothing. Get it wrong, she still removes an article of clothing. Ignore the quiz altogether and (you guessed it), she removes an article of clothing.

My kind of quiz!
