You know what they say, the couple that works together stays together. Okay probably not. In fact, probably the opposite, but nevertheless Jessica Biel is getting in on boyfriend's Justin Timberlake's fashion line by designing a range of handbags.

Biel will contribute her designs to William Rast, the label that Timberlake began with pal Trace Ayala, which specialises in denim, jackets, and tops. According to Star magazine, the actress has been busy sketching her ideas for a limited edition collection, which could soon debut on the catwalks in L.A. or New York.

"Jessica is casual when it comes to clothes, but she loves bags," a source revealed.
