How would you like Zac Efron, Vanessa Hudgens and the rest of the High School Musical gang to turn up at your school?
Well that's what's happening to kids at a school in America, where filming for High School Musical 3: Senior Year is about to start.
The first two HSMs were filmed there during the holidays, but this time filming's happening in term time.
This means that as the kids head to their lessons, they could catch a glimpse of their fave stars.
Jason Olsen, from the school in Salt Lake City, Utah, said film crews would start setting up in a couple of weeks, and shooting would begin at the end of the month.
But the kids won't be pleased to hear that lots of the filming will be taking place before and after school, to stop their lessons being disrupted.
It's thought all the main characters are returning for the third film, including Zac Efron, Vanessa Hudgens and Ashley Tisdale.
This time they'll be the oldest in the school, and Troy (Zac) and Gabriella (Vanessa), are worried about being separated from each other when they go to college.
So, along with the rest of the Wildcats, they put on a musical about their hopes and fears for the future.
