According to the website, Lovato, who entered rehab in 2010 for emotional and physical issues, has been staying in a sober living facility for more than a year. Lovato reportedly felt it was best to come home to the support system offered by the facility, especially during the filming of The X Factor.
A rep for Lovato had no comment on the report.
"The journey that I've been on has been very, very difficult over the past few months," Lovato told fans after returning home from her previous treatment. "I can't tell you how much light you guys brought into my life in probably the darkest time in my life. Without you guys, I wouldn't be here today."
