Last week pop sensation Rihanna shared a number of photos of her First Annual Diamond Ball for the Clara Lionel Foundation and it looked like the singer had a really good time.

The event took place on Dec. 11 in Beverly Hills, Calif. and the venue was full of A-List celebs like Kim Kardashian, Kris Jenner, Brad Pitt, Big Sean, Neyo, and many others.

The "Pour It Up" singer wore a red of the shoulder Zac Posen gown and she looked beyond stunning.

While one would think this star-studded event would be one memorable occasion, it looks like everyone on the guest list wasn't on his or her best behavior.

According to Daily Mail, RiRi's father Ronald Fenty was ejected from the event following his red carpet appearance and he is opening up about the accident.

Fenty said that he wasn't even able to see his daughter before he was escorted out of the event.

"I had been on the (red) carpet for the pictures, I meet a couple of famous people I knew go and talked with them, and then somebody left a chair and I stepped back and fell over, I saw my ex (Monica) look up, and within a few minutes after the picture was taken, security came up and said 'we're taking you home.'"

This isn't the first time Fenty has wrestled with alcoholism. Just last year, RiRi put her father through a $58,000 treatment at a Malibu rehab program to save him from going to jail.

Unfortunately the treatment program didn't work, but fans around the world send best wishes to Rihanna and her father during this difficult time.
