Bella Thorne has a secret arch-enemy in Hollywood.
The 18-year-old actress admits she is embroiled in a bitter feud with another well-known starlet, who she doesn't name, and avoids her "at all costs" because she is "a mean girl."
The 'Duff' star said: "I have a mean girl. 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."
The former Disney star gets on very well with her rival's family despite their issues.
She told the December/January issue of Seventeen magazine: "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."
In contrast, the 'Famous in Love' star, whose father died in a motorcycle accident when she was nine, didn't grow up wealthy and appreciates her success.
She said: "I don't think anybody really knew - it wasn't a very obvious thing. I've never really talked about it. I wasn't hiding it, and it wasn't like, 'Oh, I'm embarrassed because we don't have money.' It was, 'Oh, we don't have money, so we're going to work that much harder.' It was scary, though, because you really want those jobs. It's a different hunger when you want your family to eat."
