Forget Katy and Taylor: Your new favorite thinly veiled celebrity feud is Bella Thorne and [name]!

In an interview with Seventeenfor which Thorne appears as the December/January cover feature, the 18-year-old actress says there's one particularly menacing bully running amok in Hollywood, an offense made worse by the mystery woman's privileged upbringing.

"I have a mean girl," Thorne says​. "She's in the business, and she's very, very mean. I stay away from her at all costs. I never say hello to her. Her siblings are not mean like she is. It's just her. One of the reasons I don't like her is because she's been a billionaire since she was very little, and she's never had to work for anything in her life."

And the hum of town-wide gossip suddenly sets in...

Still, while she can't control the actions of what sounds like a relative stranger, Thorne says she's learned to manage issues within her own relationships.

"An ex of mine and I knew each other's phone passwords, and he was constantly going through my phone," she recalls​. "I learned not to do that because anything can be misread. [Boyfriend Gregg Sulkin] has my password, but he doesn't go through my phone. The ex and I also had a 'Don't talk to the opposite sex' rule, so if a guy I was working with wrote me, it would be a big problem."
