Following her self-imposed Twitter hiatus, it's suspected that Demi Lovato is back in rehab.

A new blind item from Blind Gossip that's almost transparently directed at the 'X Factor' judge suggests that the starlet took a Twitter hiatus because she's in treatment. It says that the subject blamed "gossip sites" for her problems, and if you recall, that's the subject of Lovato's Twitter rant prior to her break from the site.

Lovato addressed this herself after a previous Twitter break which the same outlet said was a coverup for rehab. Just before Valentine's Day in 2012, Lovato said she was taking a break from Twitter to go on a "cleansing retreat." Lovato denied she was in rehab at the time.

But, it's also unclear what she's up to. She spent New Year's Eve sipping coffee with friends and reflecting on her treatment, which is ongoing -- so if nothing else, her head is surely in the right place. Whatever she's up to, we hope she's staying healthy -- we're Lovatics here at PopCrush -- and we hope she's ignoring the gossip!
