Cynthia Lennon, who was married to the late Beatles legend John Lennon during his rise to fame, has died, FOX411 has learned. She was 75. 

A rep for Cynthia and John Lennon's only son, Julian Lennon, confirmed the news. 

"Cynthia Lennon passed away today at her home in Mallorca, Spain, following a short but brave battle with cancer," a statement from Julian Lennon's rep read. "Her son Julian Lennon was at her bedside throughout. The family are thankful for your prayers. Please respect their privacy at this difficult time."

Cynthia Lennon, then Cynthia Powell, met John Lennon in the early '60s in college. In 1962, the two married when she became pregnant with Julian Lennon. They eventually divorced in 1968. Cynthia Lennon remarried several times.

John Lennon memorably went on to marry Yoko Ono, and Ono remained his wife until he was murdered by a crazed fan in 1980. 

Julian Lennon told FOX411 last year, ahead of the Beatles' 50th anniversary, that he grew up living with his mom as his father traveled the world as a member of the Fab Four. 

“Anyone must remember that dad left when I was 3 years old," Julian Lennon said. "Mom and I lived out of the limelight. We lived a totally different life."

In her autobiography, Cynthia Lennon described being mistreated by her famous ex at times. But in a 2005 interview with "Good Morning America" she recalled his charisma as well.

"You couldn't resist being around him," she said. "You couldn't resist watching what he was up to. I mean, he was a total rebel. Everybody was amazed by him."

On his website, Julian Lennon shared a song and music video, featuring photos of his mother. In it he sings, "You gave your life for love/ I know you’re safe above."
