Brandon "Greasy Bear" Davis -- the man who brought you the "Firecrotch" rant -- did himself proud once again by making a total ass of himself at Paris Hilton's birthday party Saturday night, sending some of the lodging heiress' guests home early in disgust, and leaving Paris in tears.

The oily heir's boorish behavior at the lavish 26th-birthday bash began around 10:00 PM, report Rush & Molloy, when he started throwing flowers at Paula Abdul, who was supposed to sing "Happy Birthday" to Paris. Then, it was the flower-holders he was chucking. And finally, after asking Paula to "lick my [bleep]," he mocked her by talking in a fake-Arabic accent. Paula bolted early, even before crooning.

Then, Brandon decided to ingratiate himself to Courtney Love by grabbing her, making her straddle his waist, and telling her, "I want to squirt on you," never minding that Courtney's young daughter was right there.

After all this and some broken glasses and candles, Paris broke down -- and kicked Greasy out. No comment from Greasy's rep.

We're not sure which Britney Spears it was that Daniel saw a couple days back, when he added that Britney was "doing great" and "looks great."

Anna Battle Brews in Bahamas

After a week of courtroom zaniness in Florida, the Anna Nicole Smith legal saga hops over to the Bahamas, where the stakes could be even higher for Howard K. Stern, Larry Birkhead and little Dannielynn. For one, reports the New York Daily News, Howard K. Stern will be facing off against Anna's mom Virgie Arthur over the guardianship of Dannielynn, after a Bahamian judge issued an injunction stopping Stern from leaving the island with the child. Meanwhile, Birkhead arrived Sunday in the Bahamas and will be taking up the paternity battle against Stern. Still at issue is when Smith's remains will actually find their way to the Bahamas for burial next to Daniel.
