How is this knowledge known, some might ask? While there have been plenty of photos going around of Biel where she was sporting some loose fitted clothes as well as rumors and reports flying all over the place, one important person finally confirmed the news- Biel's husband, Justin Timberlake.

On Saturday, the pop star took to his Instagram page to post a rather adorable photo of his wife's pregnant belly. As she stood in a side shot with her sweater lifted up, Timberlake was crouched down kissing her stomach.

He even captioned the photo with the official pregnancy announcement that happens to come on the day that he turned 34-years-old.

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

As fans start to swoon for the couple, there is still the mystery of the baby's sex since Timberlake said that they still don't know. There was a recent report from Life & Style that said the couple was having a girl though. Apparently, the future parents couldn't resist waiting to find out.

"Jessica is more practical and said it was silly to be surprised," a source said, posted on Hollywood Life. "She wants to be completely prepared."

This news is likely not one to be trusted since Timberlake made it clear that he and his wife don't know the baby's sex. But one thing is for sure- a baby is definitely on the way!
