Strictly Come Dancing's Kristina Rihanoff and Xtra Factor host Sarah-Jane Crawford have donned capes and spandex to pose as superheroes to support this year's BBC Children In Need campaign.

Along with singer Peter Andre, choreographer Louie Spence and former rugby star and past Strictly contestant Ben Cohen they are encouraging people across the UK to buy a special "Be A Hero" badge to support this year's fundraising campaign.

Two designs have gone on sale at post offices across the country, costing £1 each with all proceeds going directly to the campaign which organisers hope will have its best year.

Members of the public will be encouraged to dress as superheroes to show their support in addition to wearing the badge.

Ben said: "It's great fun for a great cause. Whether you're at school, in the office, or even on the playing field, dig out the spandex, buy a badge and let everyone know that you're being a hero for BBC Children In Need."

Sarah-Jane said: "Wearing the badge is a simple way to be a real hero and show your support to help disadvantaged young people right here in the UK."

The Post Office has been a regular supporter of Children In Need, raising £1.3 million last year.
