A number of stars including Gary Barlow and former soccer players are recording the official England 2014 FIFA World Cup song which will debut on BBC One on March 21.
The Take That singer will record the track at Sarm Studios in West London alongside former England soccer stars and other musicians.
Lineker wrote on Twitter: ''I'm getting together one hell of a group for England's official FIFA World Cup song for @sportrelief . Teaching @GaryBarlow a thing or 2. (sic)''
Before he added: ''The boy @GaryBarlow done good for @sportrelief (sic)''.
The 'Match of the Day' presenter then attached an image of the pair of them sitting side-by-side in the studio holding a model of the World Cup trophy.
Mel C and Emma Bunton - who found fame with the Spice Girls - and former Girls Aloud member Kimberley Walsh will be among the stars contributing to the track with the help of sportsmen Michael Owen, Martin Keown and David Seaman.
The official Sport Relief Twitter account wrote: ''Ultimate Phoenix from the Flames - Sir Geoff, @MelanieCmusic @EmmaBunton @KimberleyJWalsh & a pineapple #srworldcup (sic)'', and attached an image of the females with former England international footballer Sir Geoff Hurst.
The video will make its debut on Sport Relief night on BBC One on March 21, months before the games kick off in Brazil in June.
