Lil Wayne -- 'Lakers Fan Til I Die' (Video)

"Ya'll know you won the Finals tonight if you're a Golden State Warriors fan ... but f**k all that n***a, I'm a Laker 'til my mother f**kin' death baby!"
-- Lil Wayne

Weezy was performing at Heat Ultra Lounge in Orange County, CA Tuesday night when he started talkin' basketball ... while smokin' on (what appears to be) a fat blunt.

Weezy's from New Orleans ... but has said he's been a die-hard Lakers fan ever since Kobe joined the squad. The two have become pretty tight over the years.

Might be a good time for to be a rich Lakers fan, 'cause with Jack Nicholson's enthusiasm for the team fading ... there might be some good courtside seats available next season.
