Hilary Duff made her much-anticipated return to music last week with her single, ‘Mature,’ and fans think it’s aimed at Leonardo DiCaprio!

The pop-rock tune is about a man who only dates younger women, and it’s laced with references that fans are tying to the Oscar winner.

DiCaprio, 51, is notorious for dating models 25 years old and younger, but he’s been with his current girlfriend, 27-year-old Vittoria Ceretti, since 2023, making her one of the oldest women he’s ever been linked to.

In her song, Duff sings, “She's me, I'm her in a different font / Just a few years younger, a new haircut / Very Leo of you with your Scorpio touch.”

Not only is there a mention of Leo, but he is also a Scorpio hmmm

The “Lizzie McGuire” alum’s lyrics continue, “Going down on her on your vintage rug / Bet she's so impressed by your Basquiat / And she thinks you're deep in the ways you're not.”

And the similarities to the actor continue because DiCaprio was known for owning a $9 million Basquiat that he received as a gift.

And then there are the lyrics, “Hid my car at Carbon Beach so I wasn't seen at yours / You knew better of course.”

The “Titanic” star purchased a home in Malibu in 1998, which, according to Architectural Digest, had direct access to Carbon Beach.

Duff doesn’t say if this song is about Leonardo DiCaprio or not, but she does say this song is a conversation between her current and past selves, so maybe it’s just a very, very, VERY strange coincidence that all the lyrics match up to DiCaprio.
