Rihanna's man has upgraded

New toy ... Matt Kemp gets new iPhone 4 to go with pop star girlfriend Rihanna

Free call? ... Rihanna with Matt Kemp

RIHANNA's new boyfriend knows how to show a girl a good time.

The singer spent time off from her World Tour to join MATT KEMP's pursuit of a mobile phone upgrade. The baseball star was spotted picking up a new iPhone 4 in Beverly Hills with the pop queen by his side.
The couple have been dating since December and have managed to keep their relationship fairly low profile.
After her month off, Rihanna will resume her tour in Washington at the beginning of July.
If Matt keeps up these exciting days out, she may bring forward her tour dates.
