Addison Rae is an American singer, actress and social media personality who built one of the largest followings on TikTok before making a genuine and critically acclaimed transition into music. After years of independent releases, she signed with Columbia Records in 2024 and immediately turned heads with “Diet Pepsi” — a sleek, self-aware pop track that earned platinum certification and marked her first entry on the Billboard Hot 100. The single set the tone for her debut album Addison (2025), a project rooted in hyperpop, electronic pop and sharp songwriting that debuted at number four on the Billboard 200, was named album of the year by The Washington Post and The Fader, and earned her a Grammy nomination for Best New Artist. Her rise was further cemented by collaborations with Charli XCX and appearances at Coachella, where she performed on the main stage in 2026.
