DiCaprio's girlfriend new face of M&S

Leonardo DiCaprio's model girlfriend has been unveiled as the new face of Marks & Spencer.

Bar Refaeli will front a range of Valentine's Day adverts for the high street store's underwear range.

A representative from M&S said: "Bar Refaeli has the perfect qualities to show M&S's Valentine lingerie at its best."

The 23-year-old will also appear in a summer swimwear campaign for the company.

DiCaprio and Refaeli, who met at a party four years ago, rekindled their romance in December 2007 after briefly splitting.

Israeli-born Refaeli has previously fronted campaigns for Victoria's Secret and Ralph Lauren.
