Someone’s a pop music fan! Meryl Streep was “rockin’ out” on Wednesday night at the Christopher and Dana Reeve Foundation’s annual gala at Cipriani New York, an onlooker tells PEOPLE. The Oscar winner was dancing in the aisles as Jason Derulo sang his hit, “In My Head.”

Also rocking out? Derulo’s girlfriend, Jordin Sparks, who performed later on, too, as Derulo proudly filmed.

Guests, who turned out to support the Reeve Foundation’s work to find a cure for spinal injury and improve the lives of those living with paralysis, dined on baked tagliolini with mushrooms, prime roast filet with fresh herb melange sauce,f resh seasonal ratatouille and Yukon gold sauté and a specialty cake compliments of Cake Boss star Buddy Valastro and la famiglia of Carlo’s Bakery.

Meanwhile, Streep, a close friend of the late Dana Reeve, presented the Dana Reeve Hope Award to her good friend, producer Harvey Weinstein, and the directors of The Intouchables, an inspiring film about a friendship between a quadriplegic aristocrat and the young convict who becomes his caretaker.

One of the film’s stars, Omar Sy, said he was honored to share the stage with Streep and joked that Streep could play him, though “we don’t look alike.” – Sharon Cotliar
