The actors, who are very happy romantically since their July romance started, were spotted snuggling, kissing and dancing at Hyde Lounge during Timberlake’s concert hosted by PUMA celebrating the brand’s new Forever Faster campaign.
The Modern Family star and PEOPLE’s Hottest Bachelor arrived hand-in-hand and casually dressed (save for her sky-high animal print sandals) for a double date with Vergara’s co-star Jesse Tyler Ferguson and his husband of one year, Justin Mikita.
Vergara, 42, and Manganiello, 37, were sweet and affectionate with each other on the reserved couch, with the True Blood hunk leaning in for a kiss and Vergara putting her arm around his waist.
Vergara went nuts when Timberlake sang “Rock Your Body,” and the two danced up a storm, with Vergara doing cute dances for Manganiello and instructing him, “It’s like this “.
The giddy couple reportedly giggled all night, especially when Vergara playfully showed the muscle-bound Manganiello her bulging biceps.
