Former US President Obama praised legendary vocalist Tina Turner as "unstoppable."

Obama noted in his sympathy statement that the singer was a tremendous personality who always expressed and sang the truth.

Turner, the Queen of Rock 'n' Roll, did this throughout the seasons, according to the former US president.

"Tina Turner was unpolished. She was strong, invincible and she was shamelessly herself, expressing and singing her truth in triumph and sorrow, joy and pain. "Today, we join fans worldwide in saluting the Queen of Rock and Roll and a star whose light will never dim," he said.

She passed on Wednesday at the age of 83.

Turner had a history of health problems, including cancer, a stroke, and kidney failure.

In the 1960s, she and husband Ike became prominent with songs such as Proud Mary and River Deep, Mountain High.

Tina Turner was well-known for her lewd, energetic stage performances and her husky, strong voice.

She received eight Grammy Awards and was elected into the Rock 'n' Roll the Hall of Fame as a solo artist in 2021 after being inducted with ex-husband Ike in 1991.

Following Turner's passing, here are notes of condolence sent to her family.
