Rihanna: iPhone Upgrade with Matt Kemp!

Rihanna and her boyfriend, pro baseball player Matt Kemp, play with the new iPhone 4 at the AT&T store on Thursday afternoon (June 24) in Westwood, Calif.

“He had his arm wrapped around her the whole time,” a spywitness reveals. “And she kept giving him hugs. They looked like such a cute couple.”

FYI: Rihanna is a BlackBerry user but it looks like Matt sticks to the iPhone. Guess they don’t BBM each other!
