Jaden Smith celebrated his 18th birthday by dropping a new track called Labor V2. In the song he raps about being a confused teen, as the track opens with two-minute string instrumental, followed by repeated lyrics "eighteen, eighteen, eighteen, yeah."

A confident Jaden then raps, "Confused teen, and I might be/ In between an innovator and a hype beast/ And I know you don't like me."

Along with name-checking Miley Cyrus and crowning himself the "Young Calabasas kingpin" as he raps, "Man these jokers probably think I'm Miley. Confused teen, man, I might be. In-between innovator and a hypebeast and I know you don't like me, and it's just 'cause you just like me. I chose not to wear the wife-beater with the Nikes and the white T, now everybody wearing tight jeans."

The 18-year-old actor continues, "And how many times am I telling them/ Just because you see the melanin doesn't mean that I'm a felon/ I'm here to show you the intelligence."
