Russell Simmons and his brother, Reverend Run, are likely facing legal action.

Lawyers for Rasheed Young, president of Run Athletics, sent the brothers a letter in November accusing them of funneling millions in revenue from their Pastry brand of footwear into a company Young had no part in, reports TMZ.

Young claims that Rush and Run have stolen tens of millions, and that the duo hasn’t responded at all to Young’s letter or demands.

Young demands changes in the company’s structure and his share of the shoe profits, or he says he will sue.
