Kate Moss usually shies away from interviews, but she put on a brave face for Fifty Shades of Grey.

BBC Radio 1 delivered on a promise to listeners by have the supermodel read an excerpt from the steamy novel, “Fifty Shades of Grey,” live on the air after the listeners raised $302,000 in donations for the charity, “Comic Relief.”

Kate was terrified!

“She was incredibly nervous,” a source close to Moss told the station with a weekly average audience of 6.7 million listeners. “She did panic and couldn’t stop laughing at herself for being so nervous, but she did great.”

A video of the live radio broadcast shows a visibly concerned Moss who tells radio host Nick Grimshaw, “It’s so weird, there’s a reason I don’t talk!”

What a great personality.

Kate has also got into the fundraising spirit by modelling some snazzy Red Nose Day T-Shirts, available exclusively at TK Maxx. The Red Nose Day t-shirt collection is designed by Stella McCartney.
