On-off pop queen Liz McClarnon of Atomic Kitten showed her ugly side last night as she stuck her tongue out at the G-A-Y crowd at London's Astoria.

The gesture from the sexy blonde star, despite her cutesy baby-doll dress and stockings, made her look momentarily monstrous.

But she soon returned to her usual sexy form singing alongside 'sisters' Jenny Frost, who wore a midriff-baring bra and mini-skirt combination and Natasha Hamilton in leopardskin.

The trio flit between being full-time mothers and pop stars - the band has enjoyed its ups and downs over the years - but the girls seemed thrilled to be singing together again.

"A lot has happened, but we're as close as ever - we're like sisters," Liz said recently. "In some ways it feels just the same. But then Jen starts talking about babies and it's like, 'Wow, things are really different now!'"

In the last few years the girls have been doing different things with their careers - Jenny has made a name for herself as a DJ and Liz and Natasha have embarked on solo careers. But all three say they like being together.

The sexy trio wore a series of eye-catching outfits - Jenny flaunts her wellt-oned midriff while Liz and Natasha looked feminine in baby-doll dresses and stockings

"I don't actually want to be involved in the music industry unless it's with the Kittens," Jenny revealed. "It's just not as much fun on your own."

They also confessed they would love to do a reunion tour.

Natasha added: "I would jump at the chance. Nothing can compare to the buzz of being on stage - we love it!"

The unusual gig followed their performance together at Liverpool's Number 1 Project show on 19th January, and the release of their new single "Anyone Who Had A Heart" on 28th January for a charity album.

Although the girls were performing to the G-A-Y crowd they looked as unashamedly sexy as ever
