One thing's for sure: The Hannah Montana cast loves to hug! "There's a hug line at the beginning of every show, and everyone gets a hug at the end of the show," says executive producer Steven Peterman. "It's like family." But minus the bickering. "There's no competition on our set," says Miley. "We all laugh at each other's jokes." The stars do get serious on Fridays before taping in front of a live audience. "When we have a few minutes backstage," says Billy Ray, "Miley will call us together and say a blessing." Then, once the cameras start to roll, almost anything can happen. In fact—spoiler alert!—next season "Hannah's going to have a boyfriend," says executive producer Michael Poryes. "But probably more than one!"
