Jessica Biel [1] and Justin Timberlake [2] headed out for a hike in LA on Friday as pregnancy rumors continued to swirl. Jessica was noticeably more covered up than she was last week, when she showed her stomach [3] during a shopping trip. The flash of midriff revived baby-bump speculation, which initially started with Jessica's bikini pictures [4] at the beginning of the month. The timing certainly seems right; the couple just celebrated their second wedding anniversary [5], and Justin's 20/20 Experience World Tour finishes up in early January, freeing up his schedule for possible dad duty.
