The very pregnant actress is hamming it up in Prenatal Pole Dancing, a new Funny or Die video, playing a pole dancer named Roxy Fedaro whose instructional DVD talks about the positives of pole dancing while pregnant.
Applegate and her soon to be baby daddy, 41-year-old Porno for Pyros bassist Martyn LeNoble, were engaged last February and announced they were expecting over the summer.
In the spoof, a gum-chomping Applegate grinds the pole to Christina Aguilera's "Dirrty," wears heels, ripped stockings and rubs her tummy along to the music.
"Because you're a total fatass you don't feel sexy anymore," she says in the clip, while two backup dancers—also pregnant—grind away in the background.
"Prenatal pole dancing works," she says, "because when men see pregnant women they know she's down for sex."
Applegate continues on for two minutes, rolling on the floor, patting her belly and even, uh, passing gas.
