American Idol winner Jordin Sparks is dating singer and dancer Jason Derulo. Jason and Jordin went public on Sunday night where they were spotted cuddling up at Jason’s birthday party.

People magazine reports that Jason celebrated his 22nd birthday at Phillipe Chow in Hollywood with friends and music industry folks.

“Jordin would sing to him occasionally through the night in his ear if her head was nested on his shoulder… The two left together and continued the celebration.”

We bet they did.

Meh. Jordin’s turning into such a hottie, and Jason doesn’t do it for me at all, but whatever works.
