Girls Aloud set pulses racing last night at the London leg of their new Out of Control tour.
The pop tarts fooled everyone into thinking they'd ditched their raunchy image by starting off at the 02 Arena in angelic, shimmering, full-length gowns.
The hottest girls in pop performed a number of their top hits, including Something Kinda Ooh and a cover of Britney Spears' Womanizer, with the help of some hunky, chunk back-up dancers.
The girls looked fantastic, but revealed the punishing dance moves for the show had left them black and blue.
Sarah laughed: 'It's full on from the first song, we decided to really go for it. God knows what we'll look like by the end of the tour.'
The five ladies will play a total of 30 dates after kicking off their tour in Manchester on Friday.
They play the O2 again on 23 and 24 May and then Wembley Arena on 26 and 27 May.
Meanwhile, the girls have announced they will be taking a little break to concentrate on their own projects, with Nadine and Cheryl focusing on solo material, while Sarah is interested in acting.
But don't fret, it's not the end of Girls Aloud - the group have signed a contract to produce at least three more albums, with one looking to be released in autumn 2010.
