Jessica Biel [1] kept her baby bump under wraps while leaving an office building in LA on Tuesday. The actress was clad in leggings, a loose tank top, and an oversize sweater as she made her way through the parking lot and headed to her car. Jessica and her husband, Justin Timberlake [2], have yet to officially confirm that they are expecting their first child, though Justin's former *NSYNC bandmate Joey Fatone reportedly spilled the beans [3] during an interview last month, saying, "He told me a while ago, and I kept my mouth shut, but now I can talk about it!" Jessica is back in LA after supporting Justin at his final 20/20 Experience tour stops in Las Vegas over New Year's Eve. The couple was spotted leaving on a private jet together [4] just a few days after celebrating Christmas at their home. Keep reading for the latest photos of Jessica's baby bump.
