(Cover) - EN Showbiz - Jason Derlo and Jordin Sparks are officially a couple, his representative has confirmed.

The singer celebrated his 22nd birthday in Los Angeles on Sunday night where he was seen cuddling up to the American Idol winner.

Jason was on tour in Europe on his actual birthday of September 21 but he was back in Hollywood over the weekend to spend time with his lady love.

He celebrated at celebrity hotspot Phillipe Chow with friends and music industry executives and could not seem happier to be publicly showing his love for the No Air singer.

"Jordin would sing to him occasionally through the night in his ear if her head was nested on his shoulder," an eyewitness told People magazine who announced the news.

"He was excited to spend some [quality time] with Jordin in LA. The two left together and continued the celebration."

However, during a recent trip to England, Derlo said that he had not yet found his "It Girl" as he sings about in his hit single.

But it appears he is now ready to go public with his romance with the 21-year-old pop star.

Jordin revealed her newly svelte body back in June for the cover of People Magazine's Most Amazing Bodies issue after shedding several pounds in weight.

She said at the time that she started making healthier choices, upped her intake of vegetables and drank a lot more water. (C) Cover Media
