Tony Bennett’s story about meeting his third wife, 50-year-old Susan Benedetto, may be more disturbing than heartwarming.

The 90-year-old singer (real name Anthony Benedetto) recently wrote about his first “interaction” with Benedetto in his new book, Just Getting Started, and it occurred while she was ... in utero. Yes. Really.

As Bennett explains in an excerpt shared with People magazine, he “met” Benedetto when he was introduced at age 40 to her parents, Marion and Dayl Crow, at one of his shows.

“As fate would have it, Marion was pregnant at the time with … Susan!” Bennett wrote in his book. “It’s a photo we all laugh about, knowing the incredible turn of events that followed.”

“Incredible turn of events” is certainly one way to phrase it. There are plenty of couples with big age gaps, but learning how these two initially “met” is something we didn’t exactly need to know.

Bennett met Benedetto post-birth many years later, when she was 19 and, as president of his San Francisco Bay Area fan club, asked to meet him backstage at one of his shows. (Love at second sight?)

“It tickled me that someone of her age was so devoted to my music,” Bennett wrote about his future wife. “I not only agreed to say hello to her backstage but asked her to be my date for the evening, and that’s how it all really began, foreshadowed by a backstage photo taken in 1966!”
