Justin Timberlake, Jessica Biel

Just when we thought we couldn’t love Justin Timberlake anymore he goes and celebrates his birthday in the cutest way possible – announcing he and his wife, Jessica Biel, are expecting. What made it even more adorable was the picture he posted along with the revelation.

We all knew that the Hollywood couple were expecting but the image posted on the singer’s Instagram was their first official announcement and it simply melted our hearts. Kissing Jessica Biel’s growing baby bump, Justin Timberlake, posted the following caption: “Thank you EVERYONE for the Bday wishes! This year, I’m getting the GREATEST GIFT EVER. CAN’T WAIT. #BoyOrGirl #YouNeverKnow #WeDontEvenKnow #WeAreTakingBets.”

In honour of the gorgeous couple we look at the cutest celebrity pregnancy announcements on social media:
