Justin shares nappy birthday news
It may be Justin Timberlake's birthday, but it's another birth date that's filling the actor-singer's mind - that of his future son or daughter.
The superstar shared a picture of a bulging belly - presumably belonging to wife Jessica Biel - on Instagram on his 34th birthday. He wrote that he was getting the greatest gift ever this year and added: "Can't wait."
The sex of the baby is not yet known and Grammy-winner Timberlake joked that the couple were taking bets.
It will be the first child for both Timberlake and Biel, who married in 2012.
Rumours of Biel's pregnancy have been circulating for weeks, but Timberlake's post is the first official confirmation.
