Lil Wayne Performs 'Kobe Bryant' Tribute at BET Awards, 'Rest In Peace'

Special moment from Lil Wayne on Sunday night -- he perfumed his 2009 track, "Kobe Bryant" ... with new lyrics to honor Mamba and Gianna.

It all went down at the BET Awards -- where Wayne debuted a new music video for the song, performing in front of the screen with Kobe's name on it.

The original lyrics already painted Kobe as a legend:

"He the greatest on the court ...
And I'm the greatest on the verse.
Goin' for the 4th ring like it was his 1st...
Gotta get the gleam. Do it for Kareem ...
2-4 so nice. My flow is so mean."

But, in the wake of recent events, Weezy updated the track to acknowledge the passing of Kobe and Gianna.

"Two fingers for the Mambacita. I’m screamin’ 'Black Mamba matters.'"

He continued ... "Heart goes out to Vanessa and the whole Black Mamba family."

"G-O-A-T like Kobe Bean, rest in power and hope for peace.”

Vanessa acknowledged it on her IG page -- calling the performance a "beautiful tribute."

Kobe, Gianna and 7 others passed away in a helicopter crash on January 26. He was 41. She was only 13.
