Demi Lovato has hit back at rumours she’s returned to rehab.

The tween singer, who underwent treatment at an LA facility in 2010 for an eating disorder and self-harming, insists that new reports alleging she’s checked into a Malibu health centre for “substance abuse” are “untrue.”

“Demi’s team confirmed it’s untrue,”
her rep told MTV News.

But, sadly the news that the chart-topping cutie is ditching Twitter IS true.

The ‘Skyscraper’ star, who frequently used the social networking site to keep her loyal fans up-to-date with goss on her music, social AND love life, has revealed she’s stepping away from the keyboard for a while.

“Twitter break. It's for the best actually. Who allows me to have this thing anyways?!!! I just get myself in trouble! Haha. Anyway... BYE!" she wrote after posting a series of cryptic clues suggesting she’d split from longtime beau Wilmer Valderrmama.
