Video: David Cameron appears in new One Direction video
This year's Comic Relief single by One Direction features a special guest appearance by David Cameron.
His cameo's being kept under wraps for now but the single goes on sale tomorrow.
It's a medley of two old songs - Blondie's 'One Way or Another' and 'Teenage Kicks' by The Undertones.
The Government's announced any VAT - the tax you pay when you buy things - raised from its sale will go to Comic Relief.
David Cameron isn't the first famous person to appear in a music video and we bet Ricky would love to join the 1D boys on set.
