It's been over three years since they last performed together as a group.
And on Friday night, all five members of Girls Aloud reunited to sing their new tracks Something New and Beautiful 'Cause You Love Me on Children In Need.
Wearing the same orange off-the-shoulder tulip dresses from the Something New video, the girl group strutted about on stage with a troupe of hunky male dancers in suits.
They then changed into slinky pink and gold floor-length gowns for the ballad Beautiful 'Cause You Love Me, which they debuted on radio earlier this week.
All members sang live, with Nadine Coyle showing she was still the one with the strongest vocals in the group as she belted out some big notes.
When asked how to felt to perform together, Kimberley Walsh said: 'It's great. It's so special.'
When asked about how it felt having their song selected as the official Children In Need single, Cheryl replied: 'It's just been a very special thing to be a pat of it. We feel very fortunate to be a part of it.'
Reflecting on their reunion, Nadine enthused: 'It was really great. We couldn't wait to get back to back together.
