Jessica Biel [1] is rumored to be pregnant, but since neither she nor Justin Timberlake [2] has yet to officially confirm the news [3], the only hint that fans have about the big news has been her well-hidden baby bump. However, earlier this week, Jessica shed her artfully draped jackets and sweaters when she attended one of Justin's concerts with friends. Considering that she was wearing a onesie and a tight tank top, it's hard to ignore that Jessica seems to be sporting a new figure. Indeed, the news of a possible lil' Timberlake has already started to leak out, with Justin's *NSYNC bandmate Joey Fatone reportedly spilling the beans [4] during an interview. "[Justin] told me awhile ago, and I kept my mouth shut," Joey said. "But now I can talk about it!"
