“Da Doo Ron Ron” singer Shaun Cassidy had no minute alone during his outings as female fans admired him everywhere he went.

Shaun Cassidy was a popular teen idol who stole the hearts of thousands of girls at the prime of his career.

Cassidy was rarely alone for years because of this attention, prompting him to pretend to be with someone’s sister to ward off his fans whenever he went out.

In real life, three women won the heart of the sexy teen idol – and they’re all drop-dead gorgeous.

Shaun Cassidy first shot to fame on “Hardy Boys,” but he’s no stranger to the entertainment industry. After all, his parents are Jack Cassidy and the famous actress Shirley Jones.

Even his siblings were in the industry, particularly his older half-brother David and his two younger siblings, Patrick and Ryan. Eventually, after “Hardy Boys,” Cassidy pursued a career in music.

It didn’t take long for him to shoot to fame as a teen idol. He had several platinum and gold records and often took his talents on the road while sweeping his female fans off their feet.

Being so famous took a toll on Cassidy, who felt he couldn’t do anything normally anymore. His fans were stalking his two-bedroom home in Beverly Glen, and he felt the need to move to a house with a fenced yard.

Due to this unwelcome lifestyle, he fell into depression. And while he made a choice to snap out of it, his mom got him a companion, a golden Labrador he named “Son.”

Cassidy lived with the constant fear that people would take Son away from him. He refused photograph requests with the pet for fear of it being dognapped.

The teen idol was never alone throughout his teenage and early adult years. He had to be escorted by his friends to local discos and restaurants and sometimes even needed police escorts to keep his obsessive female fans away. Even the press couldn’t get enough of Cassidy, and they watched his every move.

Interestingly, he’d often get questioned about Marie Osmond, a woman he’s never even met. Once he had enough of the questions about Osmond, he finally said: “Ah, it was just one wild night.” The media went crazy, and his statement made headlines as a direct quote from him.

Despite the flocks of women who craved his attention, only three women ever made it to Cassidy’s heart. These women are Ann Pennington, Susan Diol, and Tracey Lynne Turner.

Like many teen idols, Cassidy’s fame began simmering at one point in his career. By 1979, he married model and former Playboy bunny Ann Pennington, with whom he had three children.

At 21, Cassidy wanted nothing more than to be with his wife and children. He tried to live an everyday life away from the spotlight. The 1980s became a quiet decade for the rockstar, who kept a low profile. Unfortunately, in 1992, his marriage to Pennington ended.

After his first marriage ended, Cassidy dated actress Susan Diol for two years before they married on May 7, 1995.

It took his children years to understand who their father was in his younger years, with a daughter of his even wondering about it while watching old videos.

Diol and Cassidy had a daughter named Juliet Jones. Their marriage lasted seven years, and they divorced in 2003. It...
