Spider-Man actor Tom Holland, Game of Thrones actress Rose Leslie, TOWIE's Bobby Cole Norris, Made in Chelsea's Stevie Johnson, and Blue's Antony Costa and Lee Ryan are among celebrities backing Anthony Nolan's new campaign, #IGiveASpit.

The stars have posed in a specially designed 'I Give A Spit' t-shirt, to raise awareness of the Anthony Nolan stem cell donor register, and encourage more people to join, giving a spit sample. The campaign is also supported by Kellie Shirley, Charlotte Crosby, and Andrew Hayden-Smith.
