Alexandra Burke has had to ask for extra rooms backstage at the T4's Stars Of 2010 gig - to accommodate a large troupe of male dancers.
The former X Factor winner will perform at London's Earls Court on November 21.
An insider said: "She has had to have extra dressing rooms because she's bringing 16 sexy male dancers with her - and she's been having fun auditioning them herself."
The Saturdays, Roll Deep and Ellie Goulding have been added to the line-up, along with a special collaboration between some of the UK's top grime and hip hop artists including Professor Green and Tinie Tempah.
Also performing are Olly Murs, The Script, Pixie Lott, Example, N-Dubz, The Wanted, Jason Derulo, JLS and Mark Ronson And The Business International.
The event will be Steve Jones' last show on T4 and he is planning a big surprise.
"He is so determined to go out with a bang - he doesn't want his co-hosts Miquita Oliver and Rick Edwards to know what he's got up his sleeve so has been sneaking off for secret meets with the producers. Practicing his 'special activities' for his final farewell has left him exhausted," added the source.
Tickets for T4's Stars Of 2010 are available at www.channel4.com/t4 and the bash will be broadcast on Channel 4 and 4Music from 2.25pm on the day.
