Benjamin Millepied has become the new face of YVES SAINT LAURENT.

The 'Black Swan' choreographer - who is engaged to Natalie Portman and a principal dancer at the New York City Ballet - will appear in a campaign for The Fashion house's new men's scent, which is yet to be named.

The fragrance will be third in a line of YSL scents that includes L'Homme and La Nuit de L'Homme.

Last week, Benjamin was spotted in New York shooting the ads for the scent, which will debut in September.

Last year, Natalie - who is currently pregnant with the couple's first baby - was named as the new face of Christian Dior.

The stunning actress was unveiled as the latest spokesperson for the fashion house and has fronted campaigns for its new fragrance Miss Dior Cherie.

Parfums Christian Dior chief Claude Martinez called Natalie "charismatic and elegant", and said it was the first time the 29-year-old star had collaborated with a luxury beauty company.

However, Natalie was a little more reserved about her attributes and said: "I'm pretty casual in my beauty routine in my real life. Some might say sloppy."
