Miley Cyrus' friends think that she has taken her strict diet and exercise regime too far. The 19-year-old has lost a lot of weight in the past few months. Cyrus has been hitting the gym hard, sometimes attending two pilates classes a day. She's only been eating a measly 1,000 calories a day, reports dailystar. "Miley was getting really frustrated with the lack of film roles. So she's on a serious mission to shape up, so she can boost her career," said a source.
