Cheryl Cole 'planning girly American holiday with Sarah Harding'

is reportedly planning a 'girly' holiday to America with Girls Aloud bandmate Sarah Harding.

The 'Fight For This Love' singer has apparently been in regular contact with Harding since she entered rehab for alcohol dependency and depression last month.

According to The Sun, Cole has promised Harding a trip abroad once the latter feels well enough to undertake the outing.

"Cheryl has been there for Sarah massively. They've had some heartfelt conversations on the phone. Cheryl can identify with Sarah because she's hit rock bottom in the past too," a source said.

"It's been a long time since they've spent real quality time together so they've decided to jet off for a break. They thought America will be best as they can slip under the radar easily out there. Obviously it will be a wholesome holiday."

Fellow Girls Aloud member Kimberley Walsh has said that Harding is doing "really well" in rehab and vowed that the group are there to support her.

Harding was allegedly issued an ultimatum by the girl group that she must attend rehab if Girls Aloud were to reunite in 2012.
