A teenager got Just a Little bit more than she expected from last night's Liberty X concert when

the group invited her on stage.

The group picked Hanna MacDonald, 16, of Bognor, from hundreds of screaming fans to help sing a ballad at the Brighton Centre.

Liberty X, made up of five runners-ups from the Popstars TV talent show, were performing to a packed audience and started the night with their hit single "Just a Little".

Hanna was at Phillip Howard School, in Barnham, today but her sister Lauren, 19, said she was thrilled to be picked.

"Hanna talks to Mylene from Hearsay and emails her," she said. "She's a real celeb-spotter.

"They called her up to sing No Clouds and she knew all the words. She rang me up straight after she sang and was screaming down the phone.

"She is a bit tired today because she had to go to school but is still really pleased about it."

Liberty X will be reviewed in The Argus on Monday.
