LOS ANGELES, Oct. 1 (UPI) -- Barbara Walters apologized to Katy Perry Tuesday for reprimanding the pop star after she was late to their 2011 interview in New York.
"I shouldn't have done the interview: I was playing Madison Square Garden that same night, and I knew that the end of my marriage was coming. I was just exhausted and stressed," Perry told Billboard magazine in an interview that was widely quoted this week.
