Pop sensations The Saturdays proved they were a charitable bunch not by weighing up the amount they could give, but by taking off as much as they could.

In a flirtatious campaign for the Sports Relief Mile challenge, the fivesome stripped down to their socks to help raise funds for the cause.

In a tantalising promotion for socks set to be sold by Sainsbury’s as part of the cause, the singers donned some gold jewellery but remained firmly hidden behind red dresser doors to conceal most of their womanly assets.

Sultry Vanessa looked particularly seductive in the campaign as she directed her gaze straight down the camera lens while sporting bracelets.

Frankie, Mollie, Rochelle and Una joined their group member to front the cause, which will see thousands of Brits race their hearts out for a mile sometime between March 23rd and 25th.

Another pop celeb tied to Sports Relief is Olly Murs, who recently caused a stir when he tweeted Girls Aloud beauty Cheryl Cloe requesting her phone number.
