Tony Bennett celebrates 90th birthday with Lady Gaga

NEW YORK, Aug. 4 (UPI) -- Tony Bennett celebrated his 90th birthday at a star-studded gala Wednesday.

The legendary singer rang in the occasion with a bevy of celebrities, including pop star Lady Gaga and actors John Travolta and Bruce Willis, at the Rainbow Room in New York.

"This is a day I'll never forget as long as I live," Bennett told reporters at a lighting ceremony in his honor at the Empire State Building prior to the fête.

"To be treated this way at 90 years old, I feel like I'm 19 years old. It's a wonderful treat. It's one of the very special things in my whole life," he said. "I love life."

People reported Lady Gaga and Stevie Wonder performed Wonder's hit "Signed, Sealed, Delivered I'm Yours" at the party, while director Martin Scorsese gave a toast. Guests enjoyed two birthday cakes -- one with a New York theme and another of San Francisco.

Bennett was accompanied by his wife of nine years, Susan Crow, and his elder son, producer Danny Bennett, who presented the singer with the cakes. Bennett is also dad to son Dae and daughters Antonia and Joanna.

"I'm 90 but I still feel like I'm about 35 years old," Bennett told CNN at the bash. "I have a beautiful wife who is wonderful to me. I just love everything about her, so I'm very content with that."

Lady Gaga, who collaborated with Bennett on the 2014 album Cheek to Cheek, and other stars, including Aretha Franklin and Elton John, will honor the 19-time Grammy winner on a new NBC special. Tony Bennett Celebrates 90: The Best is Yet to Come will air Dec. 20.
