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.
