Rihanna is said to be finally putting the events surrounding last month's altercation with sometime boyfriend Chris Brown behind her - by dating Lindsay Lohan's ex boyfriend.

The pop star was reportedly on the receiving end of That 70s Show star Wilmer Valderrama's charms at the Geisha House in Hollywood last Wednesday, with Chris nowhere in sight.

A source tells the Mirror, "Rihanna looked so pretty and Wilmer could hardly take his eyes off her.

"They were chatting and laughing for ages. They looked pretty cozy and relaxed in each other's company. Wilmer was all charm and even had a bottle of champagne for Rihanna."

Wilmer dated Lindsay in 2004 but the couple later called it quits when the actor's flirtatious nature became too much to handle for the then 18-year-old Mean Girl.
