Demi Lovato has dismissed reports she's planning another stint in rehab after her publicist slammed the reports last week.
The singer underwent a spell in a treatment facility in 2010 and 2011 for "emotional and physical" issues, which she later revealed included depression and an eating disorder.
Lovato has spoken candidly about her problems since leaving rehab last year but online reports have suggested she has been seeking treatment for drug problems.
The teenager's representative quickly slammed the rumors, telling GossipCop.com "It is a crock of s**t."
And now Lovato has brushed off the claims herself on Twitter, insisting she's well and heading for a break in South America later this week .
She writes, "Don't believe the hype.... All is well! SO stoked to head to Chile in a few days!!!"
