The brunette beauty and her handsome husband celebrated Ocean Drive magazine's 21st anniversary issue at the SL Miami in South Beach, on Tuesday.
Jenna -- who's featured on the cover of the latest issue -- looked angelic in her white Grecian dress.
The new mom showed off her post-baby bod in the plunging ensemble and looked more in love than ever as she danced the night away with her "21 Jump Street" hubby.
Anyone else having some "Step Up" flashbacks?
The couple partied with a handful of their friends, and looked like they were having an amazing time together on the dance floor.
Channing let his leading lady walk the carpet alone, and dressed down for the night in jeans and a long-sleeved T-shirt. Clearly, the actor wanted all eyes on Jenna for her big night!
