Birdman Planning Huge Cash Money Tour Without Lil Wayne

Birdman's got huge plans for a Cash Money tour that will put Diddy's Bad Boy Reunion tour to shame ... and he thinks he doesn't even need Lil Wayne to make it happen.

Sources close to Birdman tell TMZ ... the Cash Money lineup will include Juvenile, Mannie Fresh, Turk, some up-and-coming acts and Baby himself, and will hopefully kick off in February. We're told there's an open invite for Weezy to join the tour ... but a lot of beef-squashing would have to be done before then.

Our sources say Birdman's been planning this all year because the 20th anniversary of the Cash Money label is coming up ... and he thinks he can outdo Diddy no problem.
