It’s easy to assume that our favorite stars have always been perfect in real life — especially during their high school days. However, it might shock you to know that some of the most popular celebrities had a rebellious streak! And unfortunately, some of them ended up getting suspended from school or even worse — expelled. Yikes!

For example, Niall Horan once admitted that he actually got suspended because he talked too much.

“I was not a bad boy but I got suspended for two days for general messing about. I talked too much which probably put me in trouble,” he said.

Niall and Zayn are just two of many celebs who couldn’t get away with their bad behavior at school — and if you think their stories were shocking, just wait until you see the rest!
