Jordin Sparks Reportedly Dating Jason Derulo

*Jordin Sparks and Jason Derulo are “officially dating,” the latter’s rep confirms to People.com

Derulo celebrated his 22nd birthday cuddling up to the “American Idol” champ on Sunday night.

Though Derulo was on tour in Europe on his actual birthday, Sept. 21, the two had a belated celebration at Phillipe Chow in Hollywood with friends and music industry executives.

A witness at the party told People: “Jordin would sing to him occasionally through the night in his ear if her head was nested on his shoulder. He was excited to spend some [quality time] with Jordin in LA. … The two left together and continued the celebration.”
