Cheryl Cole isn't the only Girl Aloud to be having relationship problems.

Nadine Coyle and Desperate Housewives star Jesse Metcalfe have split, according to sources.

Jesse jetted to London on Friday and has been hitting the London party scene hard, with one noticeable absence - Nadine.

The pair went their separate ways after trying unsuccessfully to make their rocky relationship work.

A souce says: "Nadine decided to breakup with Jesse. She's saying it's just a break but we all know it's not. They've had a very unstable relationship of late and she tried everything to make it work.

"But they want different things in life at the moment and that was the final nail in the coffin.

"She flew to LA recently and spent the entire trip with her family and gal pals. She even discussed a big girly trip to Vegas - without Jesse. She's never really done that before, he used to always be part of her plans. She's well and truly getting on with her life as a single girl."

Jesse was at the new celeb hangout No 50 Dover Street in London until the early hours of Saturday morning and, judging by the gaggle of girls swarming around him, it didn't look like he was missing Nadine.

The singer and Jesse first started going out two years ago but - in a spooky parallel to fellow Girl Aloud Cheryl's current situation - the couple split up last year over claims Jesse cheated on Nadine.

She took him back in September and Nad and her family moved to LA so she could spend more time with him.

The actor was meant to host a Desperate Housewives night in Essex club Faces last night, but he pulled out at the last minute.

A club worker said: "He cancelled, but we've got no idea why. Luckily Kelly Rowland was able to step in."

The former Destiny's Child singer Kelly sang her new single Work before retreating to the VIP area.

A fellow clubber said: "She looked like she was having a good time, dancing and chatting with a few friends, but I didn't see her drinking at all."

Anthony Costa from Blue was seen flirting with some girls outside while Chantelle Houghton drank and danced with girl pals.
