Former EastEnders star Cheryl Fergison said she was more nervous about meeting her childhood hero Donny Osmond than singing in a new ITV show.
Fergison is one of six celebrities lined up to perform on Your Face Sounds Familiar, with Osmond as a guest judge.
The show, presented by Alesha Dixon and Paddy McGuinness, challenges the celebrities to transform themselves into a different singing star chosen at random each week.
The six performers - Alexander Armstrong, Denise Lewis, Bobby Davro, Emmerdale actress Natalie Anderson, presenter Matt Johnson and Fergison - will be judged by a celebrity panel.
Fergison, who was a member of the Puppy Love star's fan club, said, "The world does not exist because my eyes will be on Mr Osmond".
Donny and Marie Osmond are set to return to the UK in the new year with a new stage show.
They joined Aled and Lorraine on the Daybreak sofa to talk about the new show and old times:
Susan Boyle has told Daybreak's Ross King that she once skipped school to watch her teenage crush Donny Osmond perform.
The Britain's Got Talent sensation was performing with her lifelong idol in Las Vegas.
