Rihanna was red hot at the Grammy Awards on Sunday night in a sheer crimson Azzedine Alaia gown. She continued her sexy style at the Supper Club in Los Angeles following the music event.

The pop star arrived at the after party in a red Lamborghini wearing a half shirt that showed off her fantastic abs, a long white skirt, and beige coat with a fur collar.

She met up with Chris Brown at the club.  On Saturday the couple attended the Roc Nation Pre-Grammy Awards Brunch at Soho House in West Hollywood, California, where they were photographed hugging each other.

Earlier that day Brown was involved in a traffic accident involving the paparazzi but wasn't injured.
