Mary J. Blige Alleges Ex Spent $420K On New Girlfriend

Mary J. Blige‘s nasty divorce from Martin “Kendu” Issacs rages on.

In court docs newly obtained by TMZ, the singer accuses Isaacs of blowing $420,000 on his girlfriend — during their marriage — and claiming the expenses were “travel charges.” Though Issacs also served as Blige’s manager, the Grammy winner claims the fees were not business-related.

Blige, 46, and Issacs announced last July they were divorcing after 13 years of marriage. Issacs is reportedly seeking more than $110,000 per month in spousal support, which includes the $5,000 he gives to his parents every 30 days.

“I am not responsible for supporting [Martin’s] parents and his children from another relationship which he lists as ongoing monthly expenses,” Blige said in the legal papers.

Blige also alleged Martin “contributes absolutely nothing” to the couple’s estate, which is said to be “underwater” with $10 million in expenses.

Though the divorce has yet to be finalized, Blige revealed in a radio interview with Power 105.1 in March that “overwhelming disrespect” led to the demise of her marriage.

“I can sense that I’m not what you want anymore,” she said. “Because now you start throwing questions around like, ‘Why don’t you cook?’ I haven’t been cooking. ‘Why you don’t wear your hair like that?’ I never wore my hair like this before … You start to realize that this man doesn’t want you and he’s just gone all the time and you’re by yourself in the relationship.”
