Hollywood actor Leonardo DiCaprio's girlfriend Bar Refaeli is the new face of Marks and Spencer’s Valentine’s Day lingerie range.

In the new ad, the 23-year-old Israeli model is seen wearing red silk bra and suspenders priced at 22 pounds in total, and another pink hearts lingerie set priced at 11 pounds.

"Bar Refaeli has the perfect qualities to show M&S' Valentine lingerie at its best," the Telegraph quoted a spokesman for the store as saying.

Although the couple have dodged questions about their relationship, they have been spotted holidaying together in Mexico, and Refaeli has also been following the actor across the world while he promotes his latest film, Revolutionary Road alongside Kate Winslet.
