Celebrity couple Justin Timberlake and Jessica Biel are hoping to work on a movie project together.
The pop hearthrob and actress want to collaborate but can't decide on which genre they want to take on.
"Justin is very keen to do a comedy while Jessica wants to do something grittier because she's concerned about her image," a source says.
Justin has squeezed roles in 'Alpha Dog', 'Southland Tales' and 'Shrek the Third' in between his music career. While Jessica's roles have included 'The Illusionist' and 'The Texas Chainsaw Massacre'.
