Ulrika Jonsson, ski-jumping flop Eddie "The Eagle" Edwards and reality TV star Amy Childs are to take to the floor in Let's Dance for Sport Relief.
The series returns next month for a five-week run with celebrities recreating classic dance scenes to help fundraising efforts.
Jonsson will be teaming up with her former Shooting Stars colleague Angelos Epithemiou for her routine while Childs will appear with her ex-Only Way Is Essex pal Harry Derbridge.
The show is noted for a jaw-dropping performance by comic actor Robert Webb who performed the routine from Flashdance in a leotard.
Other stars lined up for the next series include comics Ava Vidal, Terry Alderton and Arabella Weir while veteran DJs Tony Blackburn and David Hamilton will perform together.
Radio 1's Scott Mills will team up with chart star Olly Murs and comics Omid Djalili, Watson & Oliver, Patrick Monahan and Rowland Rivron will also take part, as the first batch of contestants was revealed.
Let's Dance for Sport Relief will again be hosted by Alex Jones and Steve Jones and returns to BBC1 on Saturday February 18.
The final takes place on March 17 and proceeds from public voting go to Sport Relief.
