Rosie Huntington-Whiteley goes topless and shows off bottom on twitter for millions

London: Rosie Huntington-Whiteley shows off the rear-ly good bum that's made her millions.

According to the Sun.co.uk, the 25-year-old posted the photo of herself wearing only a thong with a crochet top just about covering her assets.

But she must have been suffering from a bit of insecurity as she quickly took down the pic from her Twitter page.

The Devon-born supermodel is thought to be appearing as a special guest alongside modelling legends Kate Moss, 38, and Naomi Campbell, 42, at London's Olympic Closing Ceremony.

It's thought they'll trot down the catwalk in Brit designer gear including Vivienne Westwood and Alexander McQueen.

Meanwhile, she and fellow Victoria's Secret model Candice Swanepoel admitted over Twitter that they are both loving new erotic novel Fifty Shades Of Grey by British author E.L. James.

Candice tweeted a photo of the book with the comment: "A juicy read. ;)."

While Rosie agreed she was addicted to it, replying: "I don't know a women that isn't reading it!! #cantputthisonedown."
