'Rock Your Body' singer Justin stood on stage to give an acceptance speech after winning the Innovator award.
Dressed in a blue suit, Justin said: "I want to thank my best friend, my favourite collaborator, my wife Jessica at home. 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."
Jessica is expected to give birth soon, but the exact due date has been kept under wraps.
Former 'N Sync star Justin confirmed Jessica's pregnancy in January on his 34th birthday.
In a photo posted to Instagram, Justin could be seen planting a kiss on Jessica's baby bump. He captioned the photo: "Thank you EVERYONE for the Bday wishes! This year, I'm getting the GREATEST GIFT EVER. CAN'T WAIT."
