Lil Wayne....Big Trouble

Lil Wayne pled guilty to attempted weapon possession in New York this morning.

Wayne was busted on July 22, 2007 in NYC after police pulled over his tour bus because they allegedly smelled pot.

Cops say when an officer approached the bus, Wayne tossed a Louis Vuitton bag with a gun inside.

Wayne is expecting to get a year behind bars.

The rapper still faces felony drug possession and weapons charges in Arizona ... after cops found 105 grams of marijuana, 29 grams of cocaine, 41 grams of ecstasy, various drug paraphernalia and a handgun on his tour bus during a traffic stop in Yuma County back in 2008.
