Metcalfe and Coyle back on?

Desperate Housewives star Jesse Metcalfe's relationship with Girls Aloud singer Nadine Coyle is reportedly back on after they were spotted together in Los Angeles on Friday.

The couple's 14-month trans-Atlantic relationship ended earlier this year after Metcalfe was spotted holding hands with a mystery brunette following a spell in rehab. But it's reported the actor has made several attempts to win back the singers heart.
