SPOTTED: Jason Derulo at The Grove in Los Angeles, CA September 26, 2011 for an interview with Renee Bargh of Extra TV.

Jason, who just celebrated his 22nd birthday, is a happy man these days. The word on the street is that he is dating American Idol winner and cutie pie, Jordin Sparks.

The duo were spotted together celebrating Jason’s belated birthday and enjoying dinner Sunday (September 25) at Philippe Chow in Hollywood.

Last week, Jordin Tweeted “happy birthday” to the Don’t Wanna Go Home hit maker and he hit her back with “thx LOVE.” Sparks then asked, “Will you get back to the states already?? lol :P.”

CUTE ALERT!
