Girls Aloud, Take That and a special edition of Strictly Come Dancing feature on Children In Need tonight.
Terry Wogan returns with Tess Daly and Fearne Cotton to host the annual fund-raising night in the UK.
The seven-hour BBC1 show will also see McFly perform their Children In Need songs, 'Do Ya', and a cover version of Rod Stewart and The Faces’ hit 'Stay With Me'.
The Osbournes, Jack Black and Stevie Wonder are among the celebrities who will be appealing for donations and the BBC newsreaders will also give a live performance.
Other performers include the Sugababes, former 'X Factor' winner Leon Jackson, Boyzone, the Stereophonics, John Barrowman, Il Divo, Jason Donovan and Sharleen Spiteri.
Last year’s BBC Children In Need TV broadcast raised more than £19m (€22m) on the night and the 2007 total appeal topped £37m (€43m).
The show will be broadcast from the BBC Television Centre from 7pm.
