Oh no he didn't!

Apparently Drake confessed to friend Lil' Wayne that he slept with his then-girlfriend -- or so Weezy is claiming in a new book proposal that is being shopped around town, reports TMZ. While Wayne may have written about how disturbed he was by finding out that news -- Drake looked calm and cool as ever when he traveled through LAX last night in an all white ensemble.

According to Wayne's new book proposal, Drake visited him while in prison and confessed to him that the whole thing went down the day before Wayne and his then-girlfriend met. According to TMZ, Drake said, "Yeah, it's true. Don't f*ck with her like that cause I did f*ck her."  

Wayne, who was serving time at Rikers Island for gun possession, wrote about his devastation over finding out that his protege had slept with his lady love. "This is the type of sh*t that a man never wants to find out when he's locked up. Or, maybe so, cause only God knows what I would have done if I wasn't locked up right now."

The "lollipop" rapper went on, "I woke up feeling f*cked up about the f*cked up day that I had ... finding out that she f*cked Drake was the absolute worst thing I could've ever found out."

Wayne, who says he was so depressed about the news that he didn't come out of his cell for days, also wrote, "As a man, honestly, that s*** hurt ... and not because it was Drake, it could have been any man. It would've hurt the same."

The whole thing went down in 2010. But it appears they must have put the sitch behind them, the two recorded the song "Truffle Butter" together in 2014.
