Justin Bieber has a giggle fit during a concert. Celebrities — they’re just like us!

During a recent concert in Pittsburgh, PA, teen pop sensation Justin Bieber had to stop his show two different times. The first time was because two girls were fighting over his shirt (offff course it was. Those teen girls — they can be crazy).

The second time was because he could not stop laughing. When he tried to start singing “Baby” after stopping the potential riot in the audience, he messed up the intro and then could not pull it back together. It’s pretty adorable.

We try so hard not to be gaga over Bieber, but then he does something like this or his speech after he won AMAs 2010 Artist of the Year.
