The EE Official Big Top 40 from Global 4pm - 7pm
Tinie Tempah is calling on his fans to star in a special live video performance next week.
The singer wants groups of four to appear as extras in the London shoot on March 30.
Fans wanting to take part must be over 16 and willing to take part in the shoot all day.
'This is an amazing opportunity to be part of something big alongside Tinie himself,' a spokesperson for the star told The Quietus.
'While the shoot is unpaid, there will be a few surprises along the way.'
Before that, Tinie will perform with Jessie J at London's Royal Albert Hall on Sunday for the Teenage Cancer Trust.
'Can't wait for the Teenage Cancer Trust Gig @ the Royal Albert Hall on Sunday!' he tweeted. 'Everyone who got tickets is in for a Treat! :-)'
