EXCLUSIVE: <em>BOP</em> and <em>Tiger Beat</em> Volunteer at Camp Ronald McDonald’s 20th Annual Halloween Carnival!

With Halloween just around the corner, BOP and Tiger Beat caught up with all our favorite celebs at Camp Ronald McDonald for Good Times 20th Annual Halloween Carnival at the Universal Studios Backlot. The event helped raise Camp money for kids who have been affected by cancer and their families. At the Carnival, Bella Thorne showed off her awesome poison ivy costume, and we got to play with her adorable puppy! We had a blast volunteering for such a great cause, and it was totally cool hanging out with James Maslow, Caroline Sunshine, Kenton Duty, Billy Unger, Peyton List, Stefanie Scott and so many more awesome celebs!

After hitting up the festive orange carpet, the stars headed to the Celebrity Autograph Table where they chatted with all their fans and signed hundreds of autographs. Troian Bellisario took a ton of pictures with everyone, and Raini Rodriguez headed over to the pumpkin patch to read a story for her fans. After the autograph table, Amandla Stenberg headed straight for the ice cream station in her vampire costume for a snack, and we caught Booboo Stewart in line for the Carnival games!

Check out our EXCLUSIVE video above to see your favorite stars hanging out at the Carnival in their best Halloween costumes!
