Mia's best friend Lilly is all grown up! The actress reunited with costar Mandy Moore for 2004's Saved! before her far too brief appearance in The Princess Diaries 2: Royal Engagement. Heather Matarazzo has since worked on indie films like Don't Worry, He Won't Get Far On Foot and The Estate. She reportedly took a "short sabbatical" from acting to focus on philanthropic causes, and has since expanded her film credits to include writing, directing, and producing.
