The British supermodel - who is on crutches after suffering a torn ligament and arrived at the event in a golf cart - welcomed guests including Lenny Kravitz, Demi Moore, Missy Elliott, Kanye West and Kim Kardashian to the bash at the rapper's Star Island home in Miami in honour of Vladislav Doronin's recent 50th birthday.

The 250 guests were served Diddy's Ciroc vodka and Veuve Cliquot champagne and the 'I'll Be Missing You' hitmaker toasted Naomi and the Russian billionaire midway through the evening.

Diddy was also heard urging his pal Kanye to smile for photographers.

According to the New York Post newspaper, he said: "You always look moody".

Naomi - who has been in a relationship with Vladislav since 2008 - recently threw a lavish party to mark her boyfriend's birthday in Jaipur, India.

Naomi, 42, and Vladislav were joined by many famous guests including Kate Moss, Vivienne Westwood, Bob Geldof, Demi Moore and Sarah Ferguson, the Duchess of York, to enjoy a 1930s-themed dinner, with entertainment from Diana Ross, Chaka Khan and Bluesman Buddy Guy.
