New York: Singer Demi Lovato is upset after Disney channel's show 'Shake It Up' poked fun at eating disorders.

The 19-year-old actress took to twitter to express her anger and posted: 'What are we promoting here? I find it really funny how a company can lose one of their actress' from the pressures of an EATING DISORDER and yet still make (a) joke about (it).'

Later Lovato got a response from a Disney channel representative who said they were pulling out the episode she originally referred to, along with an episode of 'So Random!' that also pokes fun at food issues, reports a website
