Hilary Duff playfully reacted to rumors that her new comeback single, “Mature,” is about Leonardo DiCaprio.

“First of all, we’re getting the biggest kick out of the speculations,” the “Come Clean” songstress said while appearing as a guest on the “On Air With Ryan Seacrest” radio show.

“It’s honestly, it’s thrilling. It’s 100 percent thrilling and the internet is such a funny place. I’m obsessed with everyone and I’m seeing all the videos.”

“First of all, we’re getting the biggest kick out of the speculations,” the singer said during “On Air With Ryan Seacrest.”

Duff’s fans assumed she wrote her track about DiCaprio, 51, as she sings, “Very Leo of you with your Scorpio touch.”

Listeners speculated that the hitmaker, 38, was referring to the “Inception” star’s nickname, Leo, and his Nov. 11 birthday zodiac sign, Scorpio.

In the track, the pop star also sings about someone with a much younger woman, crooning, “She looks like she could be your daughter / Like me before I got smarter / When I was flattered to hear you say / You’re so mature for your age.”

The “Titanic” star, who is currently dating Vittoria Ceretti, 27, has been known to separate from his partners when they turn 25, or “before [their] pre-frontal cortex has fully developed.”

Additionally, Duff sings about hiding her car at Carbon Beach in Malibu, Calif., where DiCaprio owns a home.

Rumors that the actor was the man behind Duff’s song were further fueled when the Disney alum’s husband, Matthew Koma, took to social media to share a meme of DiCaprio holding the “Mature” album.

“You can’t take anything that Matthew posts seriously,” Duff added on the radio show.

“He’s the biggest troll on the planet Earth. He will lead everybody down all the roads and have the most fun doing it.”

The “So Yesterday” singer, however, refused to confirm the rumors, saying, “So, not confirming, not denying anything here.”

However, on the radio show, Duff wouldn’t confirm or deny if the track was about DiCaprio.

“Making music was a huge risk that I took at such a young age, and it was a huge part of my makeup for the longest time,” she told Vogue in an interview published on Nov. 6.

“It was hard to step away from it, but I always knew I would come back whenever the timing felt right.”

Duff is set to release her forthcoming studio album “Luck…or something” on February 20, 2026.
