The line-up for this year's 'Celebrity Fame Academy' has been revealed, with socialite Tara Palmer-Tomkinson and former 'EastEnders' star Shaun Williamson set to take part in the charity show.
Also stretching their vocal chords for Comic Relief are 'Birds of a Feather' star Linda Robson, 'Blue Peter' presenter Zoe Salmon, 'Heartbeat' star Tricia Penrose, comedy actress Miranda Hart and Mel Giedroyc from comedy duo Mel and Sue.
They will also be joined at the singing school by BBC Radio 1 DJ Colin Murray, BBC sports presenter Ray Stubbs, comedian and presenter Rowland Rivron, presenter Angellica Bell, broadcaster Fred MacAulay and comedian Tim Vine.
'Extras' stars Ricky Gervais and Stephen Merchant are set to make an appearance on the show, as supporters of contestant Williamson, who stars alongside them in the hit comedy series.
Comedian Patrick Kielty will once again host the show, with Claudia Winkleman taking over from Cat Deeley as his co-host.
Contestant Palmer-Tomkinson said: "I went to boarding school, and then another boarding school, followed by finishing school and so I know everything about living with other people."
The television star, who previously took part in reality show 'I'm A Celebrity... Get Me Out of Here', also said: "It's much more scary singing in front of millions of people than being in the jungle. I've already humiliated the whole family anyway.
Williamson said: "It's going to be a hoot. I might even moon walk on the night."
"Hopefully Ricky Gervais will come as a supporter. He's a secret fan of the show. He's really into 'Fame Academy'."
