After rocking it out on the Roseland Ballroom stage in New York City on Sunday, Justin Timberlake was immediately greeted by his gorgeous wife as the two posed for a quick pic backstage.
Justin kept it casual in flannel and a little facial scruff while Jessica looked poised in a black blazer, high-waisted cream skirt and minimal makeup.
The 31-year-old wasn't the only one showing major love for the pop crooner.
Apparently Andy Samberg, Jason Sudeikis and Olivia Wilde were also in the audience bopping their heads to J.T.'s set of "Mirrors," "Suit & Tie," and throwback tracks like "Seniorita" and "Cry Me a River."
