and Kim Porter have parted ways
, but the split isn't holding the music mogul down.
Diddy headed down to Baltimore, Md., to host the "All White Diddy Affair" at Gardel's Supper Club on Friday night, where he had a constant companion by his side: an unidentified blonde, a partygoer tells PEOPLE.
"They were friendly," says the onlooker.
According to eyewitnesses, Diddy kept a cozy position by the blonde, who wore a sparkly silver minidress and stilettos, on the 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.
Dressed in white from head-to-toe and signature dark sunglasses, Diddy arrived at the club just after midnight Saturday in one of three black Hummers. He shook a few hands and doled out a hug or two to fans, before he and the rest of his entourage made a beeline to the club's second floor VIP area.
"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," says another partygoer. "He was dancing. And so was the girl with the blonde hair – she was dancing [in front of him]. She was enjoying herself too."
Next, Diddy headed to the less-crowded and even more exclusive VIP area on the club's fourth floor, where he again settled in beside the blonde.
By 2 a.m. Diddy, the blonde and the rest of his entourage rolled out.
