Supermodel Bar Rafaeli reveals why she has been named one of the sexiest women in the world in her latest campaign for Marks & Spencer.

Leonardo DiCaprio's girl has signed a lucrative deal to appear in M&S' ads for a range of underwear designed specifically for Valentine's Day.

A spokesman for M&S tells the Daily Mail: "Bar Refaeli has the perfect qualities to show M&S's Valentine lingerie at its best."

The spokesperson added that the Israeli-born beauty will also appear in a summer swimwear campaign.

Bar's campaign with the UK high street chain follows hot on the heels of deals with Victoria's Secret and Ralph Lauren, as well as numerous cover shoots for Elle and GQ.
