Cheryl Cole has been left devastated after her husband was caught sending explicit photos and text messages to another woman.

The 'Fight for This Love' singer has been encouraged to split from her soccer player spouse Ashley Cole by her Girls Aloud bandmates and mother Joan Callaghan after it emerged he sent sexual pictures and texts to an unnamed secretary - just days after he was accused of sending similar messages to glamour model Sonia Wild.

A source told The Sun newspaper: "As far as they're concerned Ashley is holding Cheryl back. He doesn't deserve any of this worry. Sarah Harding is particularly angry, furious in fact, but all the girls are upset and see each other as sisters. They will fight tooth and claw to protect Cheryl.

"Cheryl's mum is also livid. She has said she'll support whatever decision Cheryl makes, but privately believes she deserves better."

A collection of over 300 messages were allegedly sent to the secretary by Ashley in October 2008.

One of the photographs shows him posing in front of a bathroom mirror in a pair of white briefs, while another - sent eight days later - show him gazing at the camera whilst lying on his bed.

One message wrote: "can I have 1 more of ur t**s please. (sic)"

Another read: "No its not big. Ur make me laugh. X (sic)"

Cheryl, 26, is distraught over the news, and "looked miserable" yesterday (14.02.10) as she avoided spending Valentine's Day with her husband and instead spent the day rehearsing for her BRITs performance tomorrow night (16.02.10).

A source said: "Cheryl turned up wearing sunglasses. She didn't speak to anyone and just went straight into her dressing room.

"She came on stage, did her performance and then left. She didn't back out of her performance and was in the venue for three hours but she looked miserable."
