The 41-year-old rap mogul — currently plugging new album Last Train To Paris — rubbed shoulders with fashion legend Karl Lagerfeld, 77, at the Dior Homme catwalk show.
Diddy was at the glitzy bash with his Dirty Money backing singers Kalenna Harper and Dawn Richards to see the label's Fall/Winter 2011-2012 collection.
Writing on his official Twitter account earlier Sunday, he wrote: 'ABOUT TO TAKE PARIS OVER!!! The only OFFICIAL album release party is tomorrow at L'Arc Paris!!!!!! LET'S GO!!!'
The exclusive club, on the Rue De Presbourg, is hailed as one of the hottest in the capital and is directly opposite the city's famed L'Arc de Triomphe.
Meanwhile, Diddy's new album Last Train To Paris, his fifth studio album, comes out on Monday (today).
