Hilary Duff opened up about a past age-gap relationship in her latest single, Mature, sparking conversations online about her teenage years and early romances.
The track, which she co-wrote with husband Matthew Koma, is a semi-autobiographical reflection on a relationship she had with an older man when she was just a teenager.
Fans are now speculating if the song references Duff’s former relationship with Good Charlotte frontman Joel Madden, whom she dated back in 2004.
