The mother of music and fashion mogul Damon Dash’s son has branded him a “dead-beat dad”, RadarOnline.com is exclusively reporting.

Linda Williams – who has a 19-year-old son (also named Damon Dash) – is battling her famous ex to pay court ordered payments of $425 per week to help support their son.

Williams claims that Dash Sr. - who once had an estimated fortune of $50 million – has also interfered with their son from going to college because this would mean he will have to continue to pay child support.
