The hip-hop maestro was in New York to see designer Zac Posen's spring collection but arrived after guests were seated.
Undeterred, Puffy flounced to the front with his little white pooch in tow.
According to a 3am spy, the star made it clear he wanted the front seats. "The front row was full but there was no chance Puffy wasn't going to bag the best seats."
Well, with Puff, 34, owning a 49 per cent share of Posen's gear we guess it's only fair.
Other celebs - including Claire Danes, Paris Hilton and Stephen Dorff - looked on as two people were ejected to make way for Puff.
"It didn't go down well," our spy adds. "One woman burst into tears and ran out."
Oh dear, sounds like a fashion faux pas, Diddy!

Something similar happened with Bjork a few season back...the woman she booted got put in stylist Philip Bloch's seat, and he got pissed and had her moved again. She stormed out too.
anna wintor once arrived late to the chanel couture show and she walked up the runway with someone else right past the models to get to her seat near the top of the runway
also.......at atelier versace in 2002......gwyneth paltrow, chelsea clinton, cheryl crow and heather graham were all seated in the front row, then madonna arrived and they were all shuffled down so madonna could be next to gwyneth
