The Gossip Girl beauty took to Instagram.com on Sunday (06Mar16) to share a photo of herself in a recording booth, revealing she was laying down vocals for her new film, All I See Is You.

And Blake isn't just working with any producer - she's landed iconic songwriter/beatmaker Babyface.

"I knew show choir would pay off," she wrote in the accompanying caption. "Man, did I have fun in the recording studio with @BABYFACE @2dux2 (director Marc Forster) and @hollymarilynsolem (Holly Marilyn Solem) for @alliseeisyoumovie."

She then joked about launching a pop career, adding, "Next stop, find some backup dancers QUICK. (Don't worry. I still can't sing.)"

Singer/actress Holly also shared a snap of herself with Blake and Babyface from the recording session.

"In the studio today with @blakelively and #babyface," she captioned the shot. "Nbd (no big deal). #jamz (sic)".

Further details about Blake's musical contribution to the upcoming psychological drama have yet to be revealed.

In the movie, set for release later this year (16), the actress plays a blind woman who regains her sight, only to uncover disturbing information about her life with her husband. Jason Clarke, Danny Huston and Wes Chatham co-star.
