— -- Justin Timberlake may have been solo at the iHeartRadio Music Awards Sunday, but his very pregnant wife, Jessica Biel, wasn't far from his mind.

While accepting an innovator award, the 34-year-old singer thanked Biel, referring to her as his "best friend and favorite collaborator."

He also alluded to the upcoming birth of their first child.

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

Biel, 33, is expected to give birth any day now, though her exact due date is unknown.

The couple has been mostly mum about Biel's pregnancy since Timberlake announced it in January on his 34th birthday.

"Thank you EVERYONE for the Bday wishes! This year, I'm getting the GREATEST GIFT EVER. CAN’T WAIT. #BoyorGirl #YouNeverKnow #WeDontEvenKnow #WeAreTakingBets," he wrote on Instagram alongside a photo of him kissing Biel's then-tiny baby bump.

Timberlake and Biel have been together since 2007 and were married on Oct. 19, 2012 in Italy.
