Justin Timberlake just confirmed that he and Jessica Biel are pregnant as he showed some love for his wife's baby bump on his birthday over the weekend.

The "Sexy Back" singer shared on Instagram a photo of him kissing Jessica Biel's baby bump along with the caption: "Thank you EVERYONE for the Bday wishes! This year, I'm getting the GREATEST GIFT EVER. CAN'T WAIT. #BoyOrGirl #YouNeverKnow #WeDontEvenKnow #WeAreTakingBets."

Justin Timberlake's Instagram post ended months of speculation on whether his wife Jessica Biel is really pregnant. The couple has kept their silence all throughout those almost daily reports regarding her baby bump.

Prior to Justin Timberlake's confirmation, E! News reported that Jessica Biel has been getting daily deliveries from organic farms in her effort to be as healthy as possible during her 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," the source said. "She's in her third trimester now and feeling good."

The insider added that Jessica Biel has been getting as much exercise as possible throughout her pregnancy.

The Boston Herald reported that Justin Timberlake has always expressed his goal of becoming a dad.

"Justin will be a natural dad," a friend of the couple told the publication. "And Jessica's always wanted to be a mom."

His grandmother, Sadie Bomar, also revealed in an earlier interview that Justin Timberlake told her how he's jealous of all his cousins with their little kids, and that someday he would want a family, too.

According to the insider, Jessica Biel and Justin Timberlake would become wonderful parents because they shared the same "strong family values."

The rumors that Jessica Biel is pregnant with her first child with Justin Timberlake started several months ago when the actress appeared to have a baby bump while wearing a skimpy bikini during a vacation in Maui.
