The Umbrella star Rihanna is dating a professional basketball player; she was spotted enjoying an intimate dinner with Los Angeles Lakers' star Andrew Bynum at Mastro's Steakhouse in Beverly Hills on Friday.

Rihanna whose on/off boyfriend Chris Brown has pleaded not guilty to assaulting her was nowhere to be seen.

This is the first time Rihanna, 21, has been spotted out with a man since she and Chris decided to take time away from each other to reflect on their relationship.

Chris has been charged with felony assault and making criminal threats after he allegedly punched, bit and choked Rihanna until she was unconscious in his car on February 8.

Although Rihanna and Chris, 19, initially reunited after the incident, they have not been seen together in recent weeks.
