As Kanye West would say, ‘He left Kim’s ass for a White girl!” Diddy hosted the “All White Diddy Affair” at Baltimore’s Gardel’s Supper Club on Friday night, where he spent most of the night snuggling up to an unidentified blonde in a sparkly silver minidress and stilettos.

“They were friendly,” says the onlooker.

The pair cuddled on a black leather sofas of the club’s VIP areas much of the time between sipping on $500-a-bottle Veuve Clicquot La Grande Dame Orange label champagne (”It was a special request from Diddy,” says the club staffer who served him) and chatting up admirers.

“He [Diddy] came in first and then security brought in the two girls (one of whom was the blonde) up to the VIP area on the second floor,” says an observer. “They arrived with him. They came out from the same Hummer that I saw Diddy come out earlier.”

“He seemed happy, very pleasant, and very carefree,” another mole claims. “He was dancing. And so was the girl with the blonde hair – she was dancing [in front of him]. She was enjoying herself too.”

Diddy and his date left the club around 2 am.
