A.J. Cook and Shemar Moore are spotted on the set of Criminal Minds last week in Los Angeles. The two are filming a boxing-themed episode called The Bittersweet Science, hence A.J. with her dukes up.
Also spotted on set was Shawn Hatosy and Matthew Gray Gubler - check out the pics in the gallery.
A.J. isn't just playing around by having her fists up - she really wants to get beat up this season! She told TV Guide:
"I have volunteered to get beat up! I want to get into a really bad fight this year. I'm like, 'Everyone else has gotten the crap beaten out of them! It's JJ's turn!'"
