A star-studded guest list that included John Travolta, Bruce Willis and Lady Gaga helped celebrate Tony Bennett’s 90th birthday on Wednesday.

“This particular day is the best moment in my life. The whole day has been magical. The whole world is showing up for me and wishing me well on my 90th birthday, and I can’t be more blessed than that,” Bennett said.

Others in attendance included Steve Buscemi, Katie Couric, Regis Philbin, Gayle King, Christian Siriano and a gaggle of grandchildren.

Lady Gaga and Bennett have built a lasting friendship that began when they collaborated on a version of the song “The Lady Is a Tramp” and the album “Cheek to Cheek.”

“Well, we just love one another. We’re both Italian-Americans and we understand one another. I love her family. I love everything about her and, you know, we just get along,” Bennett said.

The birthday bash was held in the Rainbow Room at Rockefeller Plaza. Willis attended with his wife, Emma Heming, and the action star admitted he used to think making it to 90 was enough. Now, after seeing Bennett’s youthful exuberance, he’s not so sure.

Travolta recalled hearing Bennett’s music from an early age. He grew up not too far away from Bennett in New Jersey and the singer’s music “saturated our home.”Musical performances from the event will be shown on the prime-time TV special, “Tony Bennett Celebrates 90: The Best is Yet to Come” in December on NBC.

“I love life. I love being alive. I think it’s a great gift to be alive, and I just cherish every moment that I’m alive,” Bennett said.
