Harry Styles recently got hit in the head with a Red Bull can that a fan threw in concert, and his mom, Anne Twist, is not happy about it! The One Direction singer's mama tweeted that fans should be "think" and be more careful at shows.

Although she's thankful that nothing bad happened, she says that it's not acceptable behavior.

Plus, she proved that she's an amazing mom by even stepping in when Directioners started bullying the girl who threw the can.

At the very least, this is all a learning lesson for fans. It's great to have fun, but not at the expense of the 1D guys' safety!

What do you think about Anne's comments! Let us know in the comments!
