He may have been known as Ol’ Blue Eyes, but what many fans forget is that Frank Sinatra was married four different times. And with the recent unfortunate passing of his widow, Barbara Sinatra, at the age of 90, and the remembrance of what would’ve been his 102nd birthday, it’s time we learn all about the wives of the late singer, who sadly died in 1998 at age 82.

Frank first tied the knot with Nancy Barbato back in 1939 when he was 24 years old and Nancy was 22 years old. The couple was together for 12 years until their split in 1951 after he had a series of affairs. During the couple’s marriage, they had three kids together: daughters Nancy, 77, and Tina, 69, and a son, Frank Sinatra Jr., who sadly died in March 2016 at age 72. Today, Nancy is 100 years old!

Very shortly after Frank’s split from Nancy, he tied the knot with Hollywood actress Ava Gardner when he was 36 years old and she was 29 years old and the two were married for six years until their divorce finalization in 1957. Despite their breakup, which stemmed from alcohol, fighting, and other matters, it’s been said that the two were soulmates and they even remained friends after their split. “In Ava, Dad had met his match,” the legend’s daughter, Tina, has said about Ava and her dad in the past. Following Ava’s death in 1990 at age 67, Frank described the loss as “very painful.” They had no children together, although it’s been said she had an abortion in the early 1950s.

During the late 1950s and early 1960s, Frank reportedly called off engagements with stars Lauren Bacall and Juliet Prowse before getting hitched to iconic model and actress Mia Farrow in 1966 when he was 51 years old and she was 21 years old (they had a 30-year age gap!). The marriage was short-lived, lasting only two years even though they stayed friends long after. And 45 years after their 1968 split, Mia admitted that Frank could possibly be the father of her son Ronan Farrow, who was born in 1987. Mia is 72 years old today.

Frank married his fourth and final wife, Barbara, in 1976 when he was 61 years old and she was 49 years old and the couple stayed together until his death in 1998, making it his longest marriage. The two didn’t have any children. May they rest in peace together.
