Watch Andrea Bocelli Go Undercover to Surprise Bride With a Wedding Serenade

The famed Italian tenor showed up at a New Jersey wedding.

Bocelli went undercover with “Good Morning America” to deliver the surprise.

“I like to do these things,” Bocelli told “GMA” prior to the surprise. “I like to give my voice like a present because my voice is a present from God to share.”

This past Halloween, Bocelli traveled to Mahwah, N.J., where Michele Walsh and Ales Dolinar were preparing to tie the knot in an afternoon ceremony.

Dolinar was aware that Bocelli was about to surprise the love of his life, adding to his jitters early on his wedding day.

“Keeping the secret was probably the worst part about getting married right now,” Dolinar said.

Only the groom, the priest, the wedding photographer and the bride's mother knew that Bocelli would be performing at the wedding.

The couple’s priest, Fr. Kevin of the Church of the Immaculate Conception in Mahwah, told “GMA” he was skeptical when Dolinar told him that Bocelli would be dropping in on the wedding.

“I said, ‘Ales, I’m kinda thinking this is a scam,’” he told “GMA.”

It was the couple's wedding photographer, Brian Delia, who identified Walsh as the bride who would be perfect for Bocelli to serenade. Walsh's family is Italian and she, like Bocelli, is an accomplished flutist.

While Delia had his camera zoomed in on Walsh to catch her reaction, Bocelli walked into the church at the end of the ceremony, to shocked reactions from the guests and wedding party.

"As soon as I heard his voice, there’s no mistaking who that is and I was just shocked and surprised," Walsh said. "I think I’m still in awe. It was amazing."

"It was the best wedding ever," she said.
