Vanessa dressed up her baby bump in a boho-inspired printed peplum dress, which she accessorized with thigh-high black boots and a matching leather purse. She completed her look with a bronze smoky eye and half-up topknot.
Nick didn't look so bad himself, pairing a black plaid button-down with gray pants and dress shoes.
Their date night was actually a group affair that included a mini girls vs. guys battle inside the celeb hot spot.

Vanessa was all about a little friendly competition. Earlier in the evening, she and Nick taped an episode of Hollywood Game Night, and the brunette beauty dutifully captured the fun on her Instagram story.
She snapped pics and videos of the crowd getting serenaded by Nick, as well as a duet from their fellow crooning contestants, Michael Bolton and Ne-Yo; a studly dance-off between Nick, JB Smoove, and Ne-Yo; and her own impressive lip syncing skills.
