Linda Pugach reportedly accidentally started the blaze while using a toaster oven at the couple's Rego Park home on Aug. 30.
The Pugaches made headlines in 1959 when Burt Pugach hired a team of hit men to throw acid in Linda Pugach's face to blind her after she left him for another man.
Burt Pugach spent 15 years in prison, then proposed to Linda on television the day after he got out. Linda Pugachaccepted and even stood by him when he allegedly had an affair and that mistress accused him of threatening her.
Their stormy romance was chronicled in "Crazy Love," a film co-directed by Dan Klores and Fisher Stevens and released this year.
The couple has been staying in a Queens hotel since the blaze destroyed their apartment and possessions.
"I just figure I have nine lives -- and I'm running out of all of them," said 70-year-old Linda Pugach.
"We're as OK as OK can be," Burt Pugach told the Daily News. "If we didn't have bad luck we'd have none at all."
