{blackbabes} Not His Tune

Los Angeles Dodger Matt Kemp must not have ended things on good terms with ex-girlfriend Rihanna. In Las Vegas for a preseason game Sunday, Kemp spent Saturday night dancing on a banquette in the downstairs Boom Box Room at club Marquee. But as soon as DJ Eric D-Lux switched to Rihanna's "Cheers," a witness told us, "Matt immediately sat down and stuck his hand up in defiance to the song. As soon as her song ended, he jumped right back up." Kemp and Rihanna dated for a year before breaking up in late December.
