The Londonderry lass was snapped kissing and cuddling the Desperate Housewives star at a petrol station in LA - despite recently claiming she was happy being single.

The leggy blonde split from her hunky boyfriend in April after 15 months when he was photographed with another girl.

However, it is understood Metcalfe was desperate to win Nadine back and invited her over to LA for a romantic dinner.

The reunion has prompted fresh speculation that Girls Aloud will break up by the end of 2007 and that Nadine will settle down with Metcalfe.

Bookmakers Paddy Power are offering odds of 2/1 that the popular girl band will announce they're splitting by the end of the year.

And that's not all the bookies are betting on after seeing snaps of Nadine and Jesse cosying up at the weekend.

It's 4/1 the couple will announce their engagement and just 8/1 that Nadine will announce there's a nipper on the way by the end of the year.

Paddy Power spokeswoman Sharon McHugh said: "Nadine must be desperately in love with Jesse. Only a few weeks ago he was spotted canoodling on the beach with a mystery lady. At this rate it seems Nads would do anything for love, and a split could definitely be on the cards."

Nadine's family have moved to LA where they plan to run an Irish bar.

She even bought a house there to be closer to him.

After Metcalfe was spotted holding hands with a mystery brunette, Nadine said she would not stay in the relationship because she wasn't the type of girl to put up with infidelity.
