Justin Timberlake and Jessica Biel Confirm Pregnancy with Cute Instagram Pic

Congratulations to Jessica Biel and Justin Timberlake!

The couple has confirmed the rumors that were swirling for a while now: the couple is expecting their first child together.

Biel had been spotted in public with what looked to be a baby bump, but both Biel and Timberlake stayed quiet about the pregnancy rumors.

However, Timberlake took the opportunity of his birthday today to make an official announcement...and post a cute photo while he was at it.

"Thank you EVERYONE for the Bday wishes!," he wrote on Instagram. "This year, I'm getting the GREATEST GIFT EVER. CAN'T WAIT. #BoyOrGirl #YouNeverKnow #WeDontEvenKnow #WeAreTakingBets."

So it would appear that the couple doesn't know the sex of the baby yet. Biel is reportedly about five months along, so if they choose to know they could find out soon.

Of course, considering the secrecy around this pregnancy from the couple (even though multiple sources, including N'Sync member Joey Fatone, confirmed the news late last year), we might not know for a while either.
