Lil Wayne -- Drake was Right ... 'F*** That Ho!'

Lil Wayne settled his beef with Drake, who slept with his girlfriend, by concluding, "F*** that ho!" ... this according to a book treatment he's shopping around to publishers.

We've obtained additional pages of the treatment, which tie up the story we told you about Friday -- that Drake visited him while he was at Rikers Island and told him the day before Weezy hooked up with his girlfriend, Drake slept with her. According to the treatment, Drake said, "I did f*** her."

Apparently, Weezy decided the GF was too loose for his taste, because in the treatment he concludes, "As a man, I'll admit that shit really f****d me up, but hey, **** that ho!" He added, "Love is blind, that's why I say make sure that bitch is a seeing eye dog."

And there's some real entertaining stuff, like when Wayne writes about guards coming into his cell and checking his nut sack, and then opening his cereal box and stomping on it.

The treatment also has proud moments, like when Wayne was down in the dumps but was uplifted by a visit from his lawyer. He says when the lawyer left, he went back to his cell to make himself some dinner. "Tonight's menu was noodle soup and a Doritos burrito. Yeah! Made it myself."

But there were low points, too. He says that same night, "The guy below me yelled all night, "Yo, f*** you Weezy!"
