RIHANNA ATTACKED OVER HER RELATIONSHIP WITH CHRIS BROWN: Evidently KATY PERRY isn't the only one upset that RIHANN has reconciled with CHRIS BROWN. Saturday an irate fan in London threw a bottle at RiRi as she was leaving a club while shouting at her about her relationship with Chris.

While the bottle didn't hit Rihanna, she fell against a metal grate trying to avoid it, and cut her leg. Her bodyguard chased the attacker and ended up hurting his leg too, which needed medical attention. The man was not caught. (PHOTO) (PHOTO)

CELEBRITY COURT - KIM KARDASHIAN SCORES COURT WIN: KIM KARDASHIAN got a big win in her divorce battle with KRIS HUMPRHIES late Friday -- an L.A. judge ruled that the case is ready to go to trial, despite Humphries' lawyer's assertion that they're having a hard time getting evidence from various TV studios.

They're due in court on April 12th for a last-ditch attempt at a settlement. If that doesn't work out -- and by all indications it won't -- they're scheduled to go to trial May 6th. Kris is seeking an annulment, saying that Kim committed fraud because she was interested only in a TV wedding special and not in actually being married.

The Nets are on track to make the post-season, which runs from April 20th to June 20th.
