He also retweeted several videos of him from the event, including one of him dancing with student Ashley Brooke.
\"I DANCED WITH @justinbieber AT MY PROM,\" Brooke wrote, alongside a Vine of her wearing a tiara and dancing with the pop star.
Baldwin also found someone to dance with, her pal and fellow model Gabby Westbrook.
Bieber and Baldwin aren't the first stars to make some high schoolers night. Check out these other celebrity prom crashers:
Selena Gomez and Demi Lovato
At the 2009 premiere of their Disney Channel movie, \"Princess Protection Program,\" Selena Gomez and Demi Lovato snuck in to a high school prom that was being held at the same venue. According to People, Gomez first stumbled on Toronto's Etobicoke Collegiate Institute prom and asked security if she could check it out. Like Bieber, his ex Gomez was just as excited about crashing the event as the students were.
\"PPP peeps and I crashed a prom tonight and danced with a highschool!! amazing!! I finally had prom!\" she tweeted afterward.
Katy Perry
A similar thing happened when Katy Perry was visiting Australia in August 2010, and a local high school was holding their prom at the same hotel where she was staying. When Perry overheard the DJ playing her song, \"California Gurls,\" the pop star snuck into the event, grabbed a mic and sang along, giving the students the surprise of their lives. But they weren't the only ones excited.
Jason Derulo
Jason Derulo not only crashed the prom at Culver City High School in Los Angeles, but the singer performed several songs on stage. And if that wasn't enough, he announced the school's prom queen and king and posed for pictures afterward. \"I'm excited, because I didn't go to my prom,\" the \"Other Side\" singer said in a video from the event. Check it out below.
