Jordin Sparks Philippe Chow dinner singer american idol

Cute new couple alert!

Jordin Sparks stepped out Sunday night looking skinnier than ever in a sheer-meets-leather LBD, and she had an interesting date by her side ... Jason Derulo!

The two looked very cozy as they hit up Philippe Chow in Hollywood to belatedly celebrate Jason's 22nd birthday.

A few days earlier, the "Tattoo" singer wished her man a happy b-day on Twitter, to which Jason replied, "thx LOVE." Jordin quickly wrote back, "Will you get back to the states already?? lol :P"

Hello, flirty!

But on his way into dinner, Jason had some interesting (and not-so-sexy!) things to tell our X17 photogs -- like how he would eat an ant for dinner. Check out some of his crazy comments in the video below.
