The Black Eyed Peas star looked every inch the rock chick as she smiled for the cameras at a screening of Scenic Route in Los Angeles on Tuesday evening (20 August).
Proud dad-to-be Josh Duhamel placed one hand on Fergie's baby bump while they walked the red carpet, and kept the other protectively around his wife.
Fergie has yet to confirm a due date for her first child although the couple have announced they are expecting a baby boy.
Throughout her pregnancy Fergie has maintained her usual cool style, favouring leathers, studs and killer heels.
Last night, she jokingly referred to herself as "rocker mommy" in a selfie taken at the premiere. Just check out those red nails and finger bling!
Josh, meanwhile, had some fun of his own via Instagram, sharing a picture of himself and Fergie with the caption: "Just picked up my hot date for the #ScenicRoute premiere. I hope she puts out…"
That will remain a mystery for now as he hasn't updated his Instagram account since!
Scenic Route is a psychological thriller about two long-time friends who find themselves stranded in the desert when their truck breaks down, testing their friendship to the max.
