Nearly three months after her son Michael’s suicide, Marie Osmond is “doing great,” her brother Donny says.
“She needed to get away and just take care of her own demons in her own mind and begin this process of repairing,” he tells Entertainment Tonight in an interview scheduled to air Wednesday. “Marie is a strong woman but she’s going to collapse – and she did.”
Osmond’s son, Michael Bryan, died on Feb. 26 after jumping from the balcony of his Los Angeles apartment. Since his death, Osmond and her brother have returned to the stage, performing their Las Vegas variety show.
