Duff\u2019s first new music in 10 years<\/a>, and is a witty track that sees her look back at her formative years and make sly jabs at a man was known for having age-gap relationships.<\/p>\nFans have been quick to assume that the person in question may be 51-year-old Leonardo DiCaprio \u2013 who has dated multiple women much younger than him over the years, and inspired jokes on social media that he ends the relationship once they turn 25.<\/p>\n
In the tongue-in-cheek lyrics across \u2018Mature\u2019, one line that stood out to fans was \u201cJust a few years younger, a new haircut \/ Very Leo of you with your Scorpio touch<\/em>\u201d, with some assuming that the reference of \u201cLeo\u201d may actually be a nod to the actor, and \u201cScorpio\u201d being his star sign.<\/p>\n
