*After Diana Ross emerged hobbling from an overseas birthday party thrown by Naomi Campbell for her boyfriend, the supermodel was herself on crutches at yet another birthday bash she hosted for her man – this time held stateside at the Florida home of Sean “P. Diddy” Combs.

On Friday, the British supermodel arrived at Diddy’s crib in a golf cart after suffering a torn ligament. She welcomed such guests as Lenny Kravitz, Demi Moore, Missy Elliott, Kanye West and Kim Kardashian to the rapper’s Star Island home in Miami in honor of Vladislav Doronin’s recent 50th birthday.

The 250 guests were served Diddy’s Ciroc vodka and Veuve Cliquot champagne and the mogul 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, he told Ye: ”You always look moody.”

As previously reported, 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. There, they were joined by the likes of Moore, Kate Moss, Vivienne Westwood, Bob Geldof and Sarah Ferguson, the Duchess of York, to enjoy a 1930s-themed dinner, with entertainment from Chaka Khan, Buddy Guy and Ross, who slipped and broke her ankle at the bash.
