They all admitted that they were nervous about slipping back into the black PVC catsuits that they became known for a decade ago.
But it seems that the Liberty X girls had nothing to worry about as they paraded around the stage with confidence at the eagerly-anticipated Big Reunion concert in London on Tuesday night.
After a tempestuous few months, Michelle Heaton seemed well and truly back on form as she revealed her midriff in a tiny black top and skintight trousers, although she did admit that the crotch of her outfit had split in rehearsals.

Holding a cane, just like she did in their video for smash hit single Just A Little back in 2002, the 33-year-old strutted around the Hammersmith Apollo stage.
But the star had obviously put her body worries behind her for the performance, wearing the most revealing outfit of all the three girls and dancing with male backing dancers.
She added a par of towering stiletto boots to the high-waisted skintight trousers and exposed a hint of cleavage through her tied-up crop top.

Band mate Jessica Taylor looked just as svelte as she did over ten years ago, wearing an all-in-one black catsuit with a halterneck.
She wore her now slightly blonder hair up in her trademark quiff on top of her head and also carried a cane around the stage.

Kelli Young, who admitted that she was scared about the on-stage outfits since giving birth to twins just seven months ago, also seemed to have slotted back into the band’s old image with ease.
All three girls were joined by fellow originals Tony Lundon and Kevin Simm who also dressed in black leather as they performed their iconic song.
Liberty X weren’t the only band to go back to their style roots at the sell-out concert, as B*Witched opted for more grown-up denim.
While Keavy Lynch paired denim dungarees with red stilettos, Lindsay Armaou opted for skinny red jeans and a denim preppy-style jacket.
They joined boyband 911, Blue and Five onstage as well as Honeyz and Atomic Kitten, who will all take part in the arena tour.
