diddy, roman abramovich,

*It’s a party rivalry!

Rap mogul Diddy and billionaire Roman Abramovich are planning New Year’s Eve parties on St. Barts.

According to Page Six, Abramovich and his girlfriend Dasha Zhukova  are planning to return to St. Barts after taking last year off from their annual NYE bash on the island.

But Diddy is vacationing on his yacht St. Barts with his family, and he’s planning a big party on the island too. And everyone knows Puff likes to get down.

Uh-oh! This could be trouble since they are both powerful men who are known to throw soirees with A-listers in attendance. Abramovich, in particular, usually has surprise performances — including in the past Red Hot Chili Peppers.

Accourding to sources, Abramovich might be teaming up with art guro Larry Gagosian yet Diddy will have celebs Kanye West and Kim Kardashian at his party.

Only when January 1, 2015 rolls around will the world know who did it bigger! If anything it will be a close call.
