Christina Applegate is going to be one sexy mama!

Currently pregnant with her first child, the 39-year-old actress plays a pole dance instructor named Roxy Fedaro in a new Funny or Die sketch.

"Just because you put on an extra 50 pounds, that doesn't mean you're not hot," Applegate says in the clip. "Prenatal pole dancing works because when men see pregnant women, they know she's down for sex."

Glee's Jessalyn Gilsig and actress Wendi McLendon-Covey also get in on the action.

"I can use these pole dancing moves anywhere," Gilsig's character explains. "A lot of men seem to like it, which is good because I actually don't know who the father of my baby is."
