Paris Hilton enjoyed a "fun night" with Prince Harry and Prince William at a bar at her family's hotel in London years ago.

She made the revelation during her appearance on Andy Cohen's "Watch What Happens Live" Wednesday alongside her mother, Kathy Hilton.

The interview touched on the Hiltons' encounters with royalty, with Kathy sharing her past meetings with Princess Diana, King Charles III and Queen Camilla.

However, the highlight came when Cohen asked about the Hiltons' interactions with Prince William and Prince Harry.

Paris admitted to meeting both princes, recalling a particularly memorable evening at the Park Lane Hilton in London.

She revealed they all had a great time at the hotel's downstairs bar, accompanied by pop star Christina Aguilera.

When pressed by Cohen about any romantic vibes or "flirty energy" between her and either of the princes, Paris dismissed such notions but affirmed that they all had a great time hanging out together.

"No, but we had a fun night," she said. "It was me, Christina Aguilera, and the boys and a group of people. It was a fun night!"

While promoting her show "Paris Hilton's British Best Friend" in the U.K. back in 2009, Paris was asked by The Sun if she would be open to dating Prince Harry.

At the time, Hilton expressed admiration for British men but ruled out a potential romance with Prince Harry due to his then-recent split with Chelsy Davy, according to People.

"I wouldn't date him out of respect for Chelsy, but in a few years, who knows?" she added.

Prince Harry went on to marry Meghan Markle in 2018. They share a 4-year-old son, Prince Archie, and a 2-year-old daughter, Princess Lilibet.

Paris and her husband, Carter Reum, share two children, a 10-month-old son, Phoenix, and a newborn daughter named London.

Paris and her mom appeared on "Watch What Happens Live" as part of their promotions for the second season of their reality series, "Paris In Love."

In addition to her revelations about a night with the British royals, Paris told Cohen that she recently surprised her family with the introduction of her daughter, London, during Thanksgiving.

The family's reaction, as shared by Paris, made the holiday celebration unforgettable.

"Paris in Love" Season 2 premiered on Peacock Thursday. Check out the trailer below.
