Abby Lee Miller isn't the only Dance Moms star who is being called out for her bossy ways!

Breaking Celebrity News exclusively spoke to a source close to teen prodigy, Maddie Ziegler, 14, who claimed that she ALSO can be a real nightmare to work with.

"A lot of other dancers cannot stand working with Maddie because she is incredibly bossy," a source who has worked on numerous shows with Ziegler told Breaking Celebrity News.

According to the source, "She seems to think she is the director of every show she is in!"

As Breaking Celebrity News previously reported, Ziegler and former teacher Miller, 50 – who recently quit Dance Moms as she faces possible prison time for fraud charges – did not see eye-to-eye and, at time, got into heated altercations on set.

Ziegler kept her thoughts to herself in her recent biography titled The Maddie Diaries: A Memoir. In fact, she did not even mention Miller! But the teen dance genius blasted her in an interview with People Magazine when she said, "I'm really glad that I did move on from that, and I did learn a lot from her and we did have some fun times. But I feel like now, I've never been happier in my life."

And although no one is surprised by Miller's departure, the source insisted to Breaking Celebrity News that Ziegler is no walk in the park either!

"Maddie is an amazing dancer and she knows this," the insider said. "But she treats a lot of people like crap and seems to think that people should bow down to her because of who she is and what she's done."
