Bobby Flay's Wife -- DIVORCE WAR ON!!! He Cancelled My Credit Cards

Bobby Flay's estranged wife says the famous chef is a brute who's using his fortune to bully her into an immoral settlement.

Stephanie March has declared war on Bobby, who filed for divorce last week. Her lawyer fired off a letter to Bobby's attorney, expressing outrage because the chef sent Stephanie a measly $5,000 check for monthly support. TMZ broke the story, they signed a prenup in 2005 which established support at $5k a month.

Stephanie's lawyer returned the $5,000 check, along with some choice words -- "We regard the support provisions of the pre-marital agreement as unenforceable (not to mention morally reprehensible)."

It gets worse. Stephanie's lawyer says Bobby was "bullying through economic warfare" by cancelling the credit card she uses for household expenses, such as groceries and pet supplies.

And there's more. Her lawyer says Bobby's trying to pressure her into issuing a joint press release saying the split is amicable. Her lawyer says that's a lie, in no small part because Bobby's demanding she sign a settlement agreement or else she can't stay in the marital home with her sick mother.

Her lawyer ends by suggesting Bobby was unfaithful, but acknowledges he denies it. Her lawyer then says Bobby tried to sling mud by suggesting Stephanie had an affair, which she says is an absolute lie.
