We knew this was coming! Miley Cyrus has fired back at reports that she's being a little beeyatch on the set of Hannah Montana in hopes of getting fired and losing the Disney shtick. "I am fully committed to Hannah Montana. It's what gave me this amazing opportunity to reach out to so many people," Miley tells People. "I couldn't do it alone. We have an amazing cast that is so supportive, including my dad who has been there for me every step of the way."

A source close to Miley is quick to back her up, saying that the rumors that Miley's being divalicious are just "a lot of craziness." Of the rumor that Miley and BFF Emily Osment have had a falling out, a source says, "Emily and Miley are like sisters. Occasionally they have disagreements but they make up and they never let it affect their work."

Miley's no stranger to the rumor mill, but the insider says that stories about her professional conduct really hurt her "because she works really hard…Miley is never late to work. Every minute of her day is planned out. When she's not shooting the movie or the series, she's recording the [Hannah Montana] soundtrack. She has a lot invested in Hannah Montana. It's not going away any time soon."
