Ryan O’Neal, the heartthrob actor who went from a TV soap opera to an Oscar-nominated role in “Love Story” and delivered a wry performance opposite his 9-year-old daughter Tatum in “Paper Moon,” died Friday, his son said.

“My dad passed away peacefully today, with his loving team by his side supporting him and loving him as he would us,” Patrick O’Neal, a Los Angeles sportscaster, posted on Instagram.

No cause of death was given. Ryan O’Neal was diagnosed with prostate cancer in 2012, a decade after he was first diagnosed with chronic leukemia. He was 82.

“He meant the world to me. I loved him very much and know he loved me, too,” Tatum O’Neal told People magazine in a statement. “I’ll miss him forever. And I feel very lucky that we ended on such good terms.”

Ryan O’Neal was among the biggest movie stars in the world in the 1970s, working with the era’s most celebrated directors including Peter Bogdanovich on “Paper Moon” and “What’s Up, Doc?” and Stanley Kubrick on “Barry Lyndon.”

He often used his boyish good looks to play men who hid shadowy or sinister backgrounds behind their clean-cut images.

O’Neal maintained a steady TV acting career into his 70s in the 2010s, appearing on “Bones” and “Desperate Housewives,” but his longtime relationship with actor Farrah Fawcett and his tumultuous family life kept him in the news.

Twice divorced, O’Neal was romantically involved with Fawcett for nearly 30 years, and they had a son, Redmond. The couple split in 1997, but reunited a few years later. He stayed at Fawcett’s side as she battled cancer, which killed her in 2009 at age 62.

With his first wife, Joanna Moore, O’Neal fathered actors Griffin O’Neal and Tatum O’Neal, his co-star in the 1973’s “Paper Moon,” for which she won an Oscar for best supporting actress. He had son Patrick with his second wife, Leigh Taylor-Young.

Ryan O’Neal nabbed a best actor Oscar nomination for the 1970 tear-jerker drama “Love Story,” co-starring Ali MacGraw, about a young couple who fall in love, marry and discover she is dying of cancer. The movie includes the memorable but often satirized line: “Love means never having to say you’re sorry.”

The actor had at times strained relationships with three of his children, including estrangement from his daughter, squabbles with son Griffin and a drug- related arrest sparked by a probation check of son Redmond.
