Widow: Tony Curtis' heart was 'ready to go'

Says he 'died peacefully… in his sleep'

Legendary screen actor Tony Curtis died early Thursday morning of cardiac arrest, his widow, Jill, tells Inside Edition.

"His heart survived many things that would have killed an ordinary man," Jill said. "This time his heart was ready to go."

She also blames his death at 85 on smoking and his chronic obstructive pulmonary disease.

“He had COPD and very bad lung problems from smoking," Jill explained. "About 30 years ago, he quit. But his lungs never worked the way they should [have]. So he was always fighting that."

Tony died at midnight Thursday morning in his Las Vegas-area home, according to published reports.

"He died peacefully surrounded by those who loved him…in his bedroom where he loved to be…I'm very happy we made the decision to bring him home from the hospital. He passed in his sleep," said his widow.

Curtis garnered an Oscar nod in 1958 for "The Defiant Ones," in which he starred with Sidney Poitier. He also headlined "Some Like it Hot" with Jack Lemmon and Marilyn Monroe.
