Britney Spears, Paris Hilton and Lindsay Lohan
Paris Hilton is remembering the good times with pals Britney Spears and Lindsay Lohan.

On Monday, the 42-year-old heiress shared two throwback photos of the trio on a night out as well as snapshots of the Bratz dolls made in their likeness.

“17 years ago… History was made. The “Holy Trinity”🔥💕 #ThatsHot,” Hilton wrote.

In the snapshots, Hilton sported a white top and her signature headband while the Freaky Friday actress, 37, wore gray leggings and a suede jacket, and the “Hold Me Closer” singer, 41, wore a short black dress.

Spears opened up in her memoir The Woman in Me about her tame outings with Hilton after Spears’ marriage to ex-husband Kevin Federline began to crumble.

“It was never as wild as the press made it out to be,” she wrote in the book.

Spears added that she “never had a drinking problem” and that hard drugs weren’t appealing to her. The pop performer’s “drug of choice,” she revealed, was the ADHD medication Adderall, which “made me high, yes, but what I found far more appealing was that it gave me a few hours of feeling less depressed.”

Hilton recounted the events leading up to the iconic paparazzi shot of Spears and Lohan in an episode of her This Is Paris podcast, saying that she and Spears had attended a friend’s party at the Beverly Hills Hotel and decided to leave and go home.

As they headed to their car, Lohan — who was in the midst of some “drama” with Hilton — approached.

“All of a sudden, I looked over, and she’s in my car. We weren’t getting along, so I was polite,” Hilton recalled. “It was really hard just to even get out of there, because I couldn’t see just with all the cameras.”

Meanwhile, in a chat with PEOPLE, Hilton praised Spears “for telling her story” in her new book, saying she’s “so proud” of the singer.

“I know how hard it can be doing a memoir because you have to really dive in and think about so many moments in your life that I’m sure you don’t even want to think about,” she said. “But it is truly such a healing experience, and writing my book [Paris: The Memoir] has changed my life in so many ways. So I’m really hoping that she feels the same way with this. I am just proud of what a strong woman she is.”
