Justin Timberlake is ready to make sweet, sweet music for fiancee Jessica Biel -- on the big screen.
The former *NSYNC standout has been tapped to compose and and serve as the music supervisor for the soundtrack to Biel's newest project, The Devil and the Deep Blue Sea. It will be the first time Timberlake -- who has been focusing on his acting career -- has released new music since his 2009 collaboration with Timbaland.
Set to begin production this fall, the film centers around a grieving widower (Jeffrey Dean Morgan) who recently lost his wife (Biel) in a car crash. Fifteen-year-old Kick-Ass star Chloe Grace Moretz costars as a young girl whom Morgan's Henry helps to build a raft to sail across the Atlantic Ocean.
Biel, 30, will also produce the project with her Iron Ocean Films partner Michelle Purple.
Also on Biel's 2012 to-do list: Tie the knot with beau of five years Timberlake, 31. Earlier this month, the couple -- who got engaged in December 2011 during a romantic mountaintop proposal in Wyoming -- were in full-tilt wedding planning mode, trying on wedding bands at a New York City jewelry boutique.
Though they didn't nab their marital accessories at the boutique, Biel has come close to deciding on her all-important wedding gown.
"Monique Lhuillier has sent over some sketches," a Biel pal tells Us Weekly. "She's Jessica's first choice."
Mulling wedding locales in California and Italy, Biel and Timberlake's "I dos" will be a lavish affair by all accounts. "It will be a big wedding," a source tells Us. "They have lots of people they want to invite."
