50 Shades of Grey, Kate Moss as Anastasia Steele? Sexy Model Reads Erotic Excerpt for Comic Relief, Cracks Up Live On BBC Radio [VIDEO]

Mstars continues to provide fans with "Fifty Shades of Grey" movie casting rumor updates daily... but here's a little fun Anastasia Steele buzz that many readers probably weren't expecting! In an effort to raise awareness for the UK-based charity Comic Relief, stunning model Kate Moss read a hot and steamy excerpt from E.L. James' hit erotica novel live on BBC radio. The 39-year-old beauty had trouble suppressing giggles as she performed the lines in the most seductive, alluring voice she could muster. Moss' short and sexy "Fifty Shades of Kate" reading soon went viral, and helped to rack in over $376,000 worth of donations!

Moss performed the erotic (and totally amusing) "Fifty Shades of Grey" reading live on-the-air with Nick Grimshaw's Radio 1 Breakfast Show on Thursday (March 14). Moss, who was joined in the studio with fellow big-names including Lily Cooper and David Walliams, took on Anastasia Steele's kinky role in support of Comic Relief, a charity which helps to fight world poverty. And apparently, she proved successful:

Moss attempted to hold back her laughter throughout the reading... until the end, when she cracks up and falls backwards onto the couch. Miss Steele's seductive duties takes a lot out of a woman! The steamy clip was just recently posted online and has already garnered several hundred hits.

The chances of Moss snagging the highly-coveted role of Anastasia Steele in the upcoming "Fifty Shades" film are very, very slim. But do fans still think she did a pretty good job, especially since she performed the rather "embarassing" reading in support of a good cause?

The entire radio show was dedicated to raising funds for Comic Relief - Grimshaw and fellow DJs Sara Cox, Greg James, and Dev all posed in their swimsuits to help raise money. Members of Little Mix and Union J were also challenged to eat a spoonful of cinnamon powder live on air, while  DJ Scott Mills had to kiss Vanessa Feltz. Grimshaw also plunged himself into a bath full of worms. But it was all worth it, with Grimshaw later tweeting:

@grimmers: "YEAHHHHHH!!! thank you SO much to everyone that donated!!! over a quarter of a milli for Red Nose Day! you're the best! xx."
