Drake was super supportive of Wayne during his Houston concert, but it was Wayne who got the crowd riled up by taking a shot at Birdman, who's refused to release "The Carter V" for years.
Wayne, who's in an epic legal battle with Birdman, ended with a call to action ... "F*** Cash Money!"
Wayne insinuated over the weekend he was done with music.
Drake made his support clear after the concert, saying, "We are fighting until you get yours. Freedom to drop music and peace of mind." Drake added this ... "I know you gave me a shot and all I can ever do with the rest of my life is return the favor. YOUNG MONEY FOREVER."
