Miley Cyrus has denied rumours she is trying to get fired from 'Hannah Montana'.

The 15-year-old star was reported to be turning up to work late and talking about how she wants to leave the hit Disney Channel show to concentrate on her music career.

But Miley insists there is no truth to the claims and thanked everyone who has supported her during her career, especially her country music singer father Billy Ray Cyrus.

She said: "I am fully committed to 'Hannah Montana'. It's what gave me this amazing opportunity to reach out to so many 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 spokesperson for the Disney Channel also vehemently denied the rumours, saying: "It's a lot of craziness.

Miley is really devoted to the show and she's really upset by the gossip. Miley is never late to work. Every minute of her day is planned out." (c) BANG
