He left his heart ... at the Beverly Hills Hotel.
Crooner Tony Bennett
swooned over his daughter Antonia, who is also a singer, in a Tweet
accompanying a photo of him giving her away to new husband Ronen Helmann at the ceremony.
"Congratulations to my beautiful daughter, Antonia," he wrote. "What a fabulous wedding."
A source tells PEOPLE that the ceremony, which Bennett attended with his wife Susan
, took place Sunday night at the Beverly Hills Hotel.
Thursday, Bennett attended an event for his Exploring the Arts charity, held at the Pacific Palisades home of Joe and Adele Laurita. He also visited the three schools that the charity is expanding to at the end of this summer.
