You've gotta learn to follow the rules!

Bella Thorne arrived back in LA yesterday with her sister after reportedly getting kicked out of her hotel room for smoking pot at the Sundance film festival, and she definitely didn't want to discuss the incident when we asked her about it! The actress hid her face as she made her way through the terminal, and was clearly not in the best frame of mind.

The wild child star and boyfriend Mod Sun, along with their entourage, were asked to leave the Mariott in Park City after staffers smelled marijuana and alerted security. "They were seen rushing out of the hotel hours before the premiere. There were so many bags, they needed a trail car to carry them," a source dished to Page Six.

The former Disney star wasn't doing herself any favors with her behavior during her time in the mountain town, either.

"Bella was just being a bratty mess, smoking every minute and literally throwing a fit whenever she was somewhere she couldn't smoke," the source added.

On second thought, maybe she was the perfect match for Scott Disick!
