Jordin Sparks and Jason Derulo have fueled rumors that they are dating, when they were pictured having dinner together over the weekend.

The pair wore big smiles as they left the Philippe Chow Restaurant in West Hollywood on Sunday night, and appeared very close. Jordin looked gorgeous in a black sheer dress, while Jason kept it casual in jeans, a white shirt and a brown leather jacket.

21-year-old Jordin joined Jason for the romantic, intimate dinner to celebrate his 22nd birthday, fuelling speculation that they are more than friends. Jordin has previously been linked to Romeo Miller after the pair were spotted having dinner and attending events together.

R&B star Jason Derulo has had some bad luck in the past with the ladies, after he once invited a woman to his suite, but discovered after she left that several personal possessions worth $80,000 (£50,000) had gone missing.

Since then he always locks up or insists on hiding away his valuables when he stays in hotels to ensure his prized possessions don't disappear.

He tells Britain's The Sun, "Some people probably get offended when I do it but who cares."
