Naomi Campbell steps out with convicted swindler at the Cannes Film Festival

Supermodel Naomi Campbell stepped out with a controversial new beau at the Cannes Film Festival in France on Wednesday - her date was a convicted swindler.

The runway queen - who has an assault conviction to her name - arrived at the premiere of new movie Che with Christian Rocancourt, a fraudster who has spent five years in prison for stealing millions of dollars from investors.

According to the New York Post, Rocancourt, 40, has impersonated members of Manhattan's famous Rothschild and Rockefeller families and pretended to be the son of actress Sophia Loren in the past, to dupe investors out of money.

Campbell celebrated her 38th birthday after the premiere, with a party aboard Sean 'Diddy' Combs' yacht.
