Sarah Harding is to dazzle viewers with her outfit on the latest edition of BBC gymnastic contest Tumble – with 200 fairy lights sewn into her leotard.

The ex-Girls Aloud star will illuminate the show with her LED costume – which also features a number of cut-out panels – while performing an acrobatic floor routine with her show partner Leon Fagbemi.

A show insider said: “Sarah is so excited about her costume as it reminds her of the good old days with Cheryl and the girls when they were on tour. She wants to give the fans what they want – glamour and a whole lot of razzmatazz.”

The second episode of the gymnastics contest will see the first contestant eliminated.

Former TOWIE star Lucy Mecklenburgh and Loose Women’s Andrea McLean are joint favourites to be given the boot at 7/4, according to bookmaker William Hill.

Ex-EastEnders star John Partridge is favourite to win the title at 13/8.

Tumble, BBC1, Saturday, August 16, 6.30pm.
