Tony Bennett may have turned 90 on Wednesday, but the jazz singer says he still feels like a teenager.

“This is a day I’ll never forget as long as I live,” Bennett told reporters Wednesday at a lighting ceremony held in honor of his birthday at the Empire State Building. “To be treated this way at 90 years old and feel like I’m 19 years old, it’s one of the very special days in my life.”

Lady Gaga, Bennett’s longtime friend and frequent musical collaborator, also turned up to help Bennett celebrate his milestone birthday.

“The whole experience is something that’s going to take me a long time to think about, and I just love every moment of what’s happening today. She’s a great friend,” Bennett told PEOPLE of having Gaga in attendance.

As for what keeps the legend feeling – and looking – so young?

“I love being alive, I love every day. It’s magic to me,” he said. “I love life.”

Bennett’s worked with some of the biggest names in music, but the star revealed there’s still one artist he’s always wanted to sing a duet with.

“Beyoncé! I understand she’s going to be a part of a gigantic special that’s being done about my life, so I’m looking forward to that,” he said.

Aside from music, Bennett has also dedicated much of his life to art. The star will have an original piece on display in the Empire State Building lobby for the next few weeks.

“I paint every day. I live right next to Central Park and love to paint there all the time. I love doing that as much as I love to sing,” he said.

Still one of the most successful musicians in the business at 90 years old, Bennett is just grateful to be able to do what he loves.

“I’ve been sold out everywhere that I’ve played throughout my life,” said the singer. “The public has been wonderful to me, I’ll never get over it.”
