• Not such good news for Kanye West: He was charged with misdemeanor battery, grand theft and vandalism yesterday in connection with the fight he had with a bunch of photographers at LAX back in September. He could face up to 2 1/2 years in jail if convicted, although that's highly unlikely. And since they're not felony charges, he isn't expected to appear in court when he's arraigned on April 14.

It looks like Alex Rodriguez's prowess on the baseball field doesn't extend to the real estate market. The Yankees third baseman, who struggled to unload his Trump Park Avenue condo and has yet to find a buyer for his Coral Gables manse, failed to get his first choice when it came time to rent an apartment at 15 Central Park West, too. Financier Henry Silverman and his much-younger girlfriend ended up snatching the $40,000-a-month, three-bedroom pad A-Rod wanted at the last minute, so he's since been forced to suffer the indignity of renting the smaller $30,000-a-month condo next door instead. And he couldn't even negotiate a discount! Poor thing. [NYO]

Looks like it's the end of the line for financier Henry Silverman and his wife Nancy.
