Expectant mama Molly Sims radiated the red carpet alongside her husband Scott Stuber.

At eight months pregnant, the model-actress, 43, looked beautiful in a blue maxi maternity dress at the premiere of her husband’s latest film, Office Christmas Party, in Westwood, Calif. on Wednesday (December 7).

On Monday, the couple promoted the film at a screening in New York City. Sims stunned in a black mini maternity dress at the NYC event.
