The "Confident" singer, who checked into rehab in 2010 at the age of 19 to be treated for alcohol and drug abuse, as well as an eating disorder and persistent self-harming - recently announced her split from Valderrama.
Lovato says she is occupying her time by going to the gym, attending Alcoholics Anonymous (AA) meetings and busying herself in the recording studio, reported Female First.
"And that's pretty much my life. And I love it. My life now consists of doing things that are bettering, that are going to better myself," she said.
