Justin Timberlake sends sweet thank you to his 'favourite collaborator,' pregnant wife Jessica Biel

If there was one person on Justin Timberlake's mind as he accepted an award at the iHeartRadio Music Awards on Sunday (March 29), he didn't keep us guessing. The doting husband and soon-to-be father gave a heartfelt shout-out to his pregnant wife, Jessica Biel, as he took to the stage in LA.

"You can't have innovation without creation, so finally, I want to thank my best friend, my favourite collaborator my wife Jessica, at home, who's watching," Justin said as he accepted the prestigious Innovator Award.

"Honey, I can't wait to see our greatest creation yet. Don't worry, Daddy's heading home right now to innovate by learning how to change a poopy diaper and get my swaddle on."

After months of speculation, Justin confirmed that his wife of two years was expecting their first child in January, on the day of his 34th birthday. He shared a photo on Instagram showing him kissing 33-year-old Jessica's pregnant tummy, 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 #We DontEvenKnow #WeAreTakingBets."

During his speech on Sunday, Justin also had some inspirational words for any youngsters watching the show.

"Growing up in school, no one ever called me anything close to an innovator," the "Take Back The Night"singer said. "They called me different, they called me weird. If you're a young person like I used to be, and you're at home watching and you're being called weird or you're being called different… I'm here tonight to tell you your critics do not count.

"Their words will fade, you won't… Dream and work hard, and maybe one day you'll find yourself standing on a stage and maybe someday somebody will be giving you an award calling you an innovator."
