'Friends With Kids': Jon Hamm, Kristen Wiig Have Sex In The Bathroom (VIDEO)

Kristen Wiig may have only been Jon Hamm's third favorite sex buddy in "Bridesmaids," but she's got his full attention in "Friends With Kids." The pair play the never-ending honeymoon couple -- sex before dinner! -- in the new romantic dramedy, written by Hamm's real-life girlfriend, Jennifer Westfeldt.

The new film focuses on Westfeldt and Adam Scott, playing two longtime besties who wake up in their 30s and realize everyone they know got married and had kids. Spurred on by biological clocks, they come up with a foolish-proof plan: have a kid together, and then look for their respective Mr. and Ms. Rights.

Filled with R-rated laughs and wryly observed commentary on modern relationships and friendships, "Friends With Kids" also co-stars Maya Rudolph, Chris O'Dowd, Megan Fox and Ed Burns. It's out in theaters on March 9.
