Rihanna 'pretty cosy' with Lohan ex

Rihanna has been spotted with Wilmer Valderrama at a Hollywood nightclub, it has emerged.

The singer was seen getting close to Lindsay Lohan's ex-boyfriend at Geisha House where the That 70s Show star hosts a weekly karaoke night, The Mirror reports.

A source said: "Rihanna looked so pretty and Wilmer could hardly take his eyes off her.

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

Rihanna is said to be on a break from her relationship with Chris Brown, following an alleged altercation between the pair ahead of last month's Grammy Awards.
