The newly married star, 40, opened up about the Parent Trap actress' happy news on the Friday, December 3, episode of her podcast This is Paris.
"I also just saw that Lindsay got engaged," Hilton — who married venture capitalist Carter Reum in November — said of the Mean Girls star, 35. "And I know that we've had our differences in the past, but I just wanted to say congratulations to her and that I am genuinely very happy for her."
The two early 2000's socialites did not always have love for each other though. In 2017, The Simple Life star alleged Lohan had crashed her and Britney Spears' infamous night out in 2006.
"It was just Brit and I out, and then [Lindsay] just, like, chased us to the car and got in. She wasn't invited," Hilton told MTV News Australia via ET at the time. "She wasn't on the list."
Now Hilton has changed her tune. During the episode, the DJ explained, "Fifteen years later, and so much has happened in the past two weeks. I got married. Britney got her freedom back and engaged. Lindsay just got engaged. I love seeing how different our lives are now, and how much we've grown up."
Hilton then took to her Instagram to reminisce about the night out as she wrote, "Wow, I can’t believe it’s been 15 years since this #iconic photo was snapped, and we were dubbed the #HolyTrinity of the 2000’s.✨"
