1. After a few vocal warm-ups, Morgan and her friends were fitted for headphones to record their own versions of Taylor Swift’s “I Knew You Were Trouble” and One Direction’s “One Thing.” “I wanted to feel like I was a performer at a concert,”explains the birthday girl.
2. Morgan’s friends sang a five-minute version of “Happy Birthday” that they had learned at camp before diving into a pink, electric guitar–shaped cake. “Every year I get a cake from Bill at Creative Cakes (creativecakesny.com). They’re the best,” says Morgan.
3. Upon arrival, guests got goosed up with sequined fedoras, gloves (à la Michael Jackson), light-up shades and VIP passes.
4. A graffiti artist was even on hand to create cool custom hats for the the tweens.
5. While music technicians mixed the newly recorded tracks, guests munched on pizza and popcorn and listened to Top 40 tunes.
6. In between singing and celebrating Morgan’s double- digit birthday, the girls crowded around the candy bar to enjoy sweet treats like cookies, licorice and lollipops.
Few tweens have the chops to land a recording contract with a studio where superstars like the Jonas Brothers, Miley Cyrus, Mary J. Blige and the actors from Pitch Perfect have sung, but guests of Pop Star Parties might as well be Grammy winners. At Deetown Studio, kids belt out their favorite songs, then download the results.
