Just six days after Jessica Biel gave birth to her first child, Justin Timberlake posted the baby's first photos on Instagram.

Both the mother and the baby looked healthy while Timberlake shared the picture his wife and son on the photo-sharing network, captioning it "The Timberlakes are ready!!! GO GRIZZ!" The Memphis-born singer even dressed his boy up in a Grizzlies shirt for the NBA Playoffs.

Biel and Timberlake became proud parents of their baby boy on 10 April 2015. They had tied the knot in October 2012 and since then many rumours had been going on about Biel being pregnant.

Later, Timberlake shared a picture of him kissing his wife's pregnant belly, announcing that they were going to have a baby very soon and that this was the best birthday gift that he could have ever received.

And no matter how big a star he is, Timberlake wants to take up his role as a father very seriously. In fact, he admitted in front of a packed audience at the iHeart Radio Innovator Awards that he is totally into learning how to change a dirty diaper.

"Honey, I can't wait to see our greatest creation yet. Daddy's heading home right now to innovate and learn how to change a poopy diaper and get my swaddle on!" said the 34-year-old singer.

Being every bit of a perfect husband, Timberlake dedicated his "Innovator Award" to his wife and also called her "best friend and favorite collaborator".
