(CBS News) Dick Clark was "one of the greatest men that I've ever known," singer Marie Osmond said Thursday.

Clark diedWednesday of a heart attack. He was 82.

Osmond fondly recalled her 40-year friendship with Clark on "CBS This Morning."

"His life speaks for itself," Osmond said. "He changed the face of music. He changed the face of television. And through it all, I told Dick, 'your face never changed.'"

Osmond said she saw Clark in Las Vegas about a month ago. She was telling him how much she loved him, when he complimented her on her Vegas show.

"He was always about the other person," Osmond said, "and not about his own amazing self."

Osmond first appeared on Clark's "American Bandstand" when she was just 13.

Osmond got a bit emotional when describing the time Clark was honored by the Daytime Emmys after he suffered a stroke.

"He was so good in his heart. It was nice in that moment to let him know how much we loved him," Osmond said. "It was an honor for me to be there. We love him."
