Looks like Pink will be foregoing the mic - no, not for her bundle of joy, but for a sex addiction.

The singer will be joining the cast of "Thanks for Sharing" alongside Mark Ruffalo and Gwyneth Paltrow.

The film is about sex addicts participating in a 12-step recovery program. The film will be directed by Stuart Blumberg, the co-writer of Ruffalo's 2010 hit, "The Kids Are All Right."

Here, Pink plays the a free-spirited friend to the insatiable Josh Gad ("Book of Mormom"). The film also stars Tim Robbins.

This will be a new role for the singer, who is even opting for her real, non-colored name, "Alecia Moore."
