P. Diddy was involved in a heated argument at his MTV Video Music Awards after-party on Sunday night after getting into it with J. Cole.

Diddy (real name Sean Combs) was co-hosting the star-studded bash with Jay Z at PH-D in New York City following the ceremony, however the night turned sour when he got into a drunken verbal altercation with fellow rapper J. Cole which then descended into a shoving match.

A source told the New York Post: 'J. Cole was saying inappropriate things to Sean Combs and his girlfriend, Cassie. Sean immediately pounced. Some pushing and shoving happened. No punches were thrown, but it was a visible disturbance. A few bottles splashed to the floor and some party goers were knocked over, falling on top of Renee Graziano from 'Mob Wives'. '

According to another eyewitness, the fracas occurred at around 3am - after both parties had enjoyed several drinks.

Diddy quickly put the incident behind him as he appeared 'untroubled' just moments later when he took to the microphone and wished girlfriend Cassie a happy birthday. Other stars who attended the lavish event included Jay Z's wife Beyonce, Rihanna, Leonardo DiCaprio and Justin Timberlake and his wife Jessica Biel.

Riri was reportedly greeted with a kiss on the cheek by rapper Drake, indicating that they are back on good terms following a messy love triangle with Chris Brown, which resulted in that infamous club brawl last year. Meanwhile, Jessica was spotted dancing up a storm with her husband''s former *NSYNC bandmates Joey Fatone and Chris Kirkpatrick, which was probably the highlight of their month if not year.
