Was it the love lagoon?

Despite Brooke Shields’ affection for the late John F. Kennedy Jr., she “never slept with him.”

“I had a crazy, crazy, crush,” Shields, 60, clarified while on “Watch What Happens Live” Thursday. “We dated, but I never slept with him.”

“I don’t know if that counts. It counted for me!” she continued. “He was lovely to meet.”

Shields also talked about watching FX’s “Love Story,” which depicted the former first son’s relationship with Carolyn Bessette Kennedy, leading up to the couple’s fatal 1999 plane crash.

“I watched it start to finish. I loved it. I thought the acting was amazing,” the “You’re Killing Me” star gushed, before noting that she didn’t have “a real love story” with the public figure.

Meanwhile, Shields’ daughter Rowan Henchy, 23, worked as a production assistant on “Love Story” and gave her mom a heads up that she was mentioned in the show.

“That was a little weird,” the “Blue Lagoon” star admitted to People earlier this week. “I was away, and my daughter called me and she says, ‘Oh my God, you’re mentioned in ‘Love Story,’” and she’s like, ‘Is it true?’”

In one scene, John (played by Paul Anthony Kelly) told Carolyn (played by Sarah Pidgeon) that, despite never dating Shields, they did share a kiss.

The “Endless Love” actress confirmed the news to her eldest child.

“I was like, ‘OK, I’d be happy to tell you all the stories if you want,’” Shields recalled, “‘but—yes.’”

In March, the mother-daughter duo poked fun at the moment in a cheeky TikTok video.

The author and model mouthed lyrics to Charli XCX’s song “Boom Clap.”

In the clip, Henchy lip-synced lyrics, while the words, “I wonder if JFK Jr. was a good kisser?” popped up on screen.

The camera then showed Shields, who was also lip syncing with the text, “One of the best,” written over the video.

Henchy, captioned the footage, “But don’t forget … they never dated.”

Shields, who is a former Calvin Klein model, was briefly linked to John in the 1980s.

In 2023, while on “The Howard Stern Show,” the mom of two said she and John went on one “real” ski date in Aspen, Colorado.

Shields called their smooch the “best kiss [she’s] ever had in [her] life,” adding that she “froze” at the thought of having sex with him.

“I was like, ‘Oh my God, you’re falling in love and if you sleep with him, he may not talk to you again,’” she recalled.

“I wasn’t playing a game, I really was just so afraid of being really hurt,” Shields insisted. “Because if I slept with him, I would have given him my entire universe, my heart, my everything.”

The former president’s son went on to marry Carolyn in 1996 and the pair had a famously volatile relationship over the years.

However, their lives were tragically cut short after the plane John was piloting crashed into the ocean off the coast of Martha’s Vineyard, Massachusetts, in July 1999. Carolyn’s sister, Lauren Bessette, was also on the plane.

For her part, Shields tied the knot with tennis star Andre Agassi in 1997, before divorcing two years later in 1999.

In 2001, the “Pretty Baby” star married Chris Henchy. Along with Rowan, the couple shares daughter Grier, 20.
