Liz McLarnon, Natasha Hamilton and Jenny Frost get their kit off for comeback show

Atomic Kitten shocked fans on Saturday when they took to the stage in their undies for a reunion concert.

The girls – Liz McLarnon, Natasha Hamilton and Jenny Frost – gave a one-off performance for London Astoria’s G-A-Y night.

They showed the audience what they’ve been missing since they split in 2004 by stripping off to their stockings and suspenders.

Liz, 26, wore a saucy white top, while Nat, 25, donned a leopard-print smock.

New-mum Jenny, 29 – who gave birth to son Casper in October – showed she’s lost her baby weight in a black bra and mini-skirt combo.

So that the girls didn’t feel underdressed, they were joined by a series of hunks wearing skimpy black briefs.
