Frankie Valli has walked (like a man) down the aisle again.

The Four Seasons frontman married his longtime love, Jackie Jacobs, in Las Vegas on Monday.

“It’s terrific to have found love once again at this stage of my life,” he told People.

The bride, 60, and groom, 89, exchanged vows at the Westgate resort with no other attendees.

Valli’s signature song, “Can’t Take My Eyes Off You,” played in the background during the private ceremony — and he even sang parts of it into Jacobs’ ear, according to the magazine.

The legendary New Jersey-born crooner wore a classic navy suit with a white button-down shirt, while the former CBS marketing executive stunned in a simple white wedding dress with her hair pinned up.

The couple met at a restaurant in Los Angeles in 2007 but did not start dating until 2015.

“We kept in touch by phone until he called me and asked for a date,” Jacobs shared, “and we’ve been together ever since.”

This is Valli’s fourth marriage.

He first wed Mary Delgado in 1958. They had two daughters, Antonia and Francine, before divorcing in 1971. (Francine died of a drug overdose in 1980 at age 20.)

The “Sherry” singer then married MaryAnn Hannigan in 1974. They separated in 1982.

His third union came in 1984 when he said “I do” to Randy Clohessy, with whom he went on to welcome three sons, Francesco, Emilio and Brando. They divorced in 2004.

“This was a tough breakup because of the boys,” comedian Stewie Stone told People in 2008 of Valli’s third failed marriage.

“I really don’t know why it didn’t work out. People don’t get married to get divorced,” Stone added. “Maybe people weren’t meant to be together forever.”
