Let's Dance 2012 for Sports Relief continues on BBC One tonight, with arguably its biggest line up yet!
They'll be against SMart telly presenter Kirsten O'Brien and comics Arabella Weir and Omid Djalili.
Also taking to the dance floor are young TV stars Tyger Drew-Honey of Outnumbered and Dani Harmer of Tracy Beaker.
And if that line up isn't enough to get you tuning in, Tinchy Stryder and Pixie Lott will be in the studio performing their new single 'Bright Lights'.
Comedians Tim Minchin, Ed Byrne and Katy Brand will also be hand to offer their view and critique from the judging panel.
