Sean Kingston had a bad night this week when his Bentley got repossessed while he was out partying in Hollywood.

According to TMZ, Sean valeted his Bentley at the Mondrian Hotel in West Hollywood, when a repo crew immediately backed in their tow truck to take it away.

Before it was towed away, Sean came out of the hotel and got into an argument with the repo man, telling him he “paid for it already."   Surprisingly that didn't work.
