R&B diva Toni Braxton’s recent bankruptcy filing is possibly due to her show at Flamingo Las Vegas, a close relative tells TMZ. According to the “close relative,” Braxton obtained show insurance through Lloyd’s of London for her act at the Flamingo Las Vegas Hotel & Casino back in 2006. After Braxton’s heart condition sidelined her in the middle of the contract, she was forced to pull the plug, but she was still on the hook to the hotel for a large amount of cash. Expecting Lloyd’s to cover the loss, but the company did not, claiming Braxton had an undisclosed, preexisting medical condition, rendering the policy void. As Singersroom previously reported, Braxton filed Chapter 7 bankruptcy in California, claiming she owes between $10 million and $50 million in unpaid bills. The bankruptcy filing is her second.
