Celebrities Katie Price, Marcus Brigstocke and Joe Swash are amongst the latest names to be revealed as taking part in Let's Dance for Comic Relief 2011. Waterloo Road actor Philip Martin Brown will also be joining on the trio on the programme - which returns to BBC One on Saturday 19 February.

Celebs already confirmed to be appearing on the laugh out loud dancing show include: Noel Fielding, Russell Kane, Colin and Justin, Penny Smith, Andi Osho, Ed Byrne, Rebecca Front, Lulu, Caroline Flack, Adrian Edmondson, Lee Nelson and an Eighties super group of Toyah Wilcox, Clare Grogan, Chesney Hawkes and Limahl.

It was also previously revealed that Alex Jones - presenter of the BBC's evening magazine programme The One Show - will join Steve Jones to host this year's series.

Jo Wallace, BBC executive producer, said: "We're so excited to announce these latest names, they add to an already fantastic line-up and this year's show is shaping up to be a fun packed, high energy event all in the name of charity."

Across three weeks, Let's Dance will see the acts (a mix of solo dancers, duos and groups) from the world of comedy and entertainment pay homage to and perform some of the world's most iconic dance routines in front of a live studio audience. Each week the stars will be battling it out to wow viewers with their moves, and secure a place in the grand final in week four.

As always, each act will work with a team of choreographers to master the dance moves from famous routines including Beyonce's Crazy In Love, I Love To Boogie from the musical Billy Elliot and Michael Jackson's Bad.

There will be a weekly rotating panel made up of comedians, some of whom are former contestants, who will review each of the performances. The panel of three, together with the viewers, will vote for their favourite two acts to go through to the final and be in with a chance to be crowned champion of the dance floor!
