Justin Timberlake and Jessica Biel have been coupled up for a while -- and now they've decided to take their relationship to the next level. No, that's not the ringing of wedding bells you hear, it's the jingling of cash registers; J.T.'s invited Jess to help design bags for his William Rast label. Well, you know the old saying: the couple that makes bags together ...

But seriously, William Rast is that rare beast in the celebrity fashion jungle -- a line that people might actually buy even if it wasn't connected to someone famous. We hope Jessica doesn't do anything to mess with that mojo. Much as we love her, she hasn't exactly been a shining example of natural style lately. As she's trotted the globe from festival to festival promoting her latest movie, "Easy Virtue," each of her red carpet outfits has been more disastrous than the last. We're still traumatized by the sight of her in what looked like a trash bag but was allegedly a Vuitton gown.

Maybe it's because she's got one of the most heavenly bodies in Hollywood, but Jessica just doesn't seem to have a feel for clothes. Or not yet, anyway. But bags are a different story ... and we're hoping this one has a happy ending.
