LAS VEGAS, CALIFORNIA: Francesco Stephen Castelluccio aka Frankie Valli, the celebrated lead vocalist of the iconic band The Four Seasons, exchanged vows with Jackie Jacobs, a former CBS marketing executive, in a joyous ceremony held in Las Vegas on Monday, June 26. After maintaining a friendship for 16 years, the 89-year-old singer and the 60-year-old marketing executive decided to make their bond official.

Reflecting on the momentous occasion at the Westgate Hotel, Valli expressed his joy, stating, "It's terrific to have found love once again at this stage of my life," as told to PEOPLE. Opting for an intimate affair, the couple said their wedding vows surrounded by the pure serenity of an empty guest list. Reportedly, the singer's hit track 'Can't Take My Eyes Off Of You' played in the background while they were getting married. This marked the fourth marriage for Frankie Valli, so let's have a look at his past relationships.

Mary Mandel

Valli's first marriage was to Mary Mandel, also known as Mary Delgado. They were married from 1957 to 1971. When they met, Mandel already had a 2-year-old daughter named Celia. Over the course of their marriage, the couple welcomed two daughters, Antonia and Francine. Tragically, the family experienced profound loss when Celia died after falling off a fire escape in 1980. Just six months later, they faced another devastating blow as their daughter Francine succumbed to a drug overdose. As per reports, Mandel died in 2007.

Mary Ann Hannigan

In 1970, Valli crossed paths with Mary Ann Hannigan, who became his second wife. They got married in June 1974 and decided to reside in New Jersey, close to Valli's daughters. He said in April 1975, "She was a pal when I needed one but because I'd been hurt before, I resisted what I was feeling about her," to PEOPLE. However, their marital journey came to an end in 1982, with the specifics surrounding their divorce remaining undisclosed.

Randy Clohessy

For the third time, Valli embarked on the path of matrimony with Randy Clohessy in 1984. Clohessy entered Valli's life after his second marriage concluded. Together, the couple experienced the joy of raising three sons, Francesco and twins Brando and Emilio. Although their relationship primarily stayed away from the public eye, it was revealed in October 2004 that Clohessy and Valli had decided to part ways, signaling the conclusion of their 20-year marriage.

Despite the ups and downs in his personal life, Valli's unwavering passion for music continues to captivate audiences, firmly establishing him as an iconic figure in the music industry. 'A Touch of Jazz' was the last studio album released by the falsetto singer in June 2021.
