Nadine Coyle back with Metcalfe?

Nadine Coyle has sparked rumours of a reunion with Desperate Housewives actor Jesse Metcalfe.

The Girls Aloud singer was spotted having a romantic meal with Jesse at the One Sunset restaurant in Hollywood, earlier this week. Afterwards, they made their way to Metcalfe's car and he drove them away.

An onlooker told The Mirror: "The chemistry between them was sizzling - they looked like a couple in love and like they were having a really good time. Nadine was absolutely stunning in a low-cut skimpy black dress and she was really tanned. She was smiling loads and seemed really happy."

Nadine dumped Jesse in April, after newspapers claimed that he was cheating on her. Last month, Metcalfe admitted that he was desperate for Coyle to take him back.
