Lil Wayne questions Bryan 'Birdman' Williams' accounting records

Rapper Lil Wayne wants to scrutinise the accounts of his former mentor Bryan 'Birdman' Williams amid allegations he failed to split a $70 million advance.

The Lollipop hitmaker has been locked in a bitter legal battle with his Cash Money Records boss since the beginning of 2015, when he filed a $51 million suit accusing Birdman of withholding money allegedly owed to him for his long-delayed album Tha Carter V.

His lawyers have now filed court papers questioning how Williams managed to burn through a $100 million check cut by executives at parent company Universal Music Group as part of a distribution deal, which was supposedly intended to be shared with Wayne, who heads up Cash Money subsidiary Young Money Entertainment.

Williams states the majority of funds was spent on royalty payments, marketing and recording expenses - but Wayne wants to see receipts for everything.

According to TMZ.com, representatives for Williams have already submitted over 20,000 pages of financial documents to court, but Wayne's attorneys insist they do not include any information about how the $70 million was spent, and they are seeking further access to his accounts.
