Even since her days as a child actor, Emma Watson has exuded a certain poise in her public appearances. So it was endearing to see her blush in a recent interview when her phone rang and revealed that her ringtone is Tina Turner’s “Steamy Windows.”

“That is so embarrassing!” Watson said. “That is my phone. That is Tina Turner.”

The interviewer, Mark Heyes of ITV, laughed and called it “the best ringtone ever.”

“Well, I’m glad that I’m forgiven because it was Tina Turner otherwise that would have been terrible,” Watson said.

Watson was promoting her new movie Colonia, which opened in the U.S. in April and is now arriving in the U.K.
