Lil Wayne (Weezy) Performs in Vegas [Video]

He is Weezy, but he ain't asthmatic -- Lil Wayne threw the crowd into a frenzy last night when he made a surprise appearance during Drake's concert in Las Vegas.

Wayne came out to his track with Drake called "Miss Me" -- and based on the sheer pandemonium from the crowd ... we'd say the answer is clearly "yes."
