Teen star Miley Cyrus can endure all criticisms about 'salvia', lap dancing and her love life, as long as her weight is left alone.

She took out all her anger on her Twitter posts, which basically sums up the negative effects of weight bullying.

"By calling girls like me fat, this is what you're doing to other people," Cyrus tweeted last Friday, together with a photo of a woman suffering from an eating disorder, to stress her point. "I love MYSELF & if you could say the same you wouldn't be sitting on your computer trying to hurt other."

With another photo attachment, this time Marilyn Monroe's, she continues, "Proof that you can be adored by thousands of men even when your thighs touch."

Backing up to what seems like a budding 'woman empowerment' movement is fellow Disney star and best friend, Demi Lovato.

The 'Skyscraper' singer tweets, "AMEN!" "@MileyCyrus god i love you. SO DO YOU!!! And whoever called you that has it coming."

"I will destroy any one that ever calls you the F word," she adds. "You have the SEXIIIESTTT curvyyyy body! I LOVE IT!"

It's good to see these girls sticking out for each other in these times of intrigue, because there's an even bigger issue they need to face - an anonymous user on Reddit who claims to be a former child actor, is apparently dishing more dirt on them.

Lovato may need some serious encouragement here, for she is the one worst hit by these.

"We had a weird encounter at an event ... wherein she referred to me as 'that fat a-' and a 'fat skank'. I'll give her that she was probably struggling with her [eating disorder] at the time, but it was really pretty unnerving and d-ish," referring to the singer-actress' attitude.

The source adds, "Basically, Demi's cocaine habit was pretty much the worst-kept secret at Disney for a few years."

This child actor also emphasized what we already knew about Miley Cyrus.

"I remember hearing from people who worked on Hannah Montana that she fought with her family nonstop. In terms of drugs, it was fairly well-known that she was (and remains) a big stoner, and of course she started drinking fairly young (15/16 - not like Drew Barrymore young) and by the time she was 17, she was smoking cigarettes fairly often, but I never really heard about her getting into hard drugs."

However, those were just snippits of the revelations. The source goes on to reveal details about other Disney stars, and ultimately on how the Mouse House manages its stars.

Sounds like another Twitter word war!
