In the long standing legal battle with Birdman ... Weezy claims in legal docs he tried to ink a deal with Chanel West Coast on his Young Money Label ... but negotiations went south when Cash Money refused to give the official sign off.
Here's what's odd -- back in 2013 it was reported Chanel signed with Young Money ... and is still featured on their website as an artist. According to Wayne's docs though ... the deal never went through ... so it's unclear whether Chanel was ever officially brought on.
Wayne makes it clear though ... Birdman is getting in the way of business and ultimately costing the company a ton of money.
We reached out to Birdman for comment ... so far no word back.
