KELSEY GRAMMER LOSES TENNIS PARTNER

SLAMMER GRAMMER:

The love match just ended between "Frasier" star Kelsey Grammer and his regular tennis doubles partner! The guys were practicing for a UCLA "Night At The Net" charity game when Kelsey raced after a ball and -- WHACK!! -- accidentally slammed the dude's head with his racquet, raising a huge lump! GET A NEW PARTNER, the guy told Kelsey! (Tennis, anyone?)
