Kate Moss put in a model performance on air when she read an extract from steamy best- seller Fifty Shades Of Grey to raise money for Comic Relief.
The catwalk star had to suppress giggles as she read from the EL James work during Nick Grimshaw’s Radio 1 Breakfast Show.
She was joined in the studio by other big names including Lily Cooper and David Walliams as they raised more than £250,000.
Grimshaw and fellow DJs Sara Cox, Greg James and Dev all posed in their swimwear to raise money for the charity appeal and members of Little Mix and Union J were challenged to eat a spoonful of cinnamon powder live on air.
Fellow DJ Scott Mills had to kiss Vanessa Feltz, before Grimshaw took a dip in a bath of worms.
