In a not-so-classy move, Sean Combs urged people to buy his favourite brand of vodka - after reportedly comparing other drinks to 'pee'.

The hip-hop mogul, the celebrity ambassador for Ciroc vodka, was said to have encouraged guests at Greenhouse to try the label.

According to a source, the 40-year-old rapper went on to refer himself "Ciroc Obama", the New York Post reported.

He reportedly said: "If you're not drinking Ciroc vodka, then you're drinking pee pee."

Combs holds a multiyear strategic partnership worth up to 100 million dollars with Ciroc and apparently receives a 50 percent share of profits, it was said. (ANI)
