Paris Hilton knew she was making pop culture history when she decided to star in the now infamous 2005 Carl’s Jr. commercial — so much so that she kept a little piece of it for herself.

“I was actually just with Chris Applebuam, the director, a few weeks ago and we were talking about it, because it was just such an iconic moment in pop culture history,” Hilton, 44, exclusively told Us Weekly on July 11, while promoting Carl’s Jr.’s new Queso Crunch Burger and subsequent campaign with influencer Alix Earle.

“We were just, like, looking at all the Polaroids that we took during the fittings, which was a lot of fun,” the “Stars Are Blind” singer continued. “I, of course, kept the gorgeous swimsuit that I was wearing on top of the Bentley. Yeah … I just love how timeless that commercial was. That’s something that people always remember and talk about. It’s just so sexy and hot. I love it.”

In 2005, the heiress appeared in a commercial for the fast food company, in which she seductively washed a Bentley while donning a revealing swimsuit and posing on top of and beside the car. Periodically, Hilton would take large bites of the food chain’s Spicy BBQ Six Dollar Burger.

“That’s hot,” the commercial ended, capitalizing on Hilton’s signature phrase.

“It was so much fun,” Hilton told Us of her experience filming the commercial. “I think it’s the most iconic one that they’ve ever made.”

Since she had such a blast partnering with Carl’s J. in the early aughts, it was a no-brainer for Hilton to return via a cameo alongside Earle to highlight the fast food chain’s latest signature burger.

“It’s so fun just to come back and do this with Alix,” Hilton told Us. “She’s so sweet and so much fun. I love that it’s just, it’s like a legacy and coming [back] to return as an OG is always fun for me.”

Hilton went on to explain that she has worked with Earle on a few projects before, in addition to hanging out “a couple times” previously.

“I love her,” she added. “I think she is just fun, unapologetic. She’s authentic and she’s just a very cool girl. I really love her.”

In addition to returning to her re-living her internet-breaking Carl’s Jr. days, Hilton told Us she’s busy recording new music for her upcoming album.

“I’m actually [in] the studio now. I just recorded the second song yesterday, for my new album, and I’m going back today,” she dished. “So the next couple weeks I’m actually in the studio every single day recording the third album. I am very, very excited. The songs are iconic. They are bops and people are going [to] lose it over this new album. It’s so sick. I’m so proud of it.”
