The former Lizzie McGuire star released her 2025 single, "Mature," that November, and fans are still clamoring over the song's lyrics and their meaning. The track is a recollection of a past, unknown relationship when Hilary dated an older man. Naturally, the song prompted listeners to contemplate whom she is singing about. "Mature" is Hilary's first piece of music she's released in a decade, and fans can't wait for her to perform live in the new year.
