Fans have become excited as Justin Timberlake has confirmed that his wife, actress Jessica Biel, is pregnant.

Posting a picture on his Instagram account on the occasion of his 34th birthday, Timberlake announced the pregnancy. In a picture, where he is seen kissing the bare pregnancy bump of his wife, he wrote saying, "Thank you EVERYONE for the Bday wishes! This year, I'm getting the GREATEST GIFT EVER. CAN'T WAIT.#BoyOrGirl #YouNeverKnow #WeDontEvenKnow#WeAreTakingBets."

Timberlake and Biel, who have been dating since 2007, got married in a private ceremony in Italy in 2012.

Although Biel was spotted with a bump in public, there was no confirmation from either of the parties. However, a very close friend of Timberlake, Joey Fatone, who also happens to be his former bandmate, broke the news early in December.

Speaking on the pregnancy to In Touch Magazine, he said, "He told me a while ago, and I kept my mouth shut. But now I can talk about it. Jessica is awesome, and Justin is a kid at heart. They'll have fun."

The couple, however, is not very keen on knowing the gender of the baby. An inside source speaking to Hollywood Life on the gender of the baby, said, "Jessica is more practical and said it was silly to be surprised. She wants to be completely prepared."

An inside source, talking about Biel's pregnancy, said, "She has been having deliveries from local farms so she can eat fresh organic produce and be as healthy as possible throughout the pregnancy. Being healthy is really important to her. She is very aware of the importance of eating well. She wants to have the best pregnancy possible.," according to E! News.

Also, according to the website, Biel is said to be in her third trimester.
