She means business.

Demi Lovato opted to go to an "aggressive" and "constructive" rehab following her overdose, rather than kicking back at a cush facility that caters to celebrities, Us Weekly reports.

"This is not her first rodeo. She doesn’t want to feel like things are being handed to her. For Demi, this is a strength test,” a source dished to the mag.

"The rehab she is in is much more drill sergeant-esque. It’s not nurturing. At places like Promises, you live on the beach and go horseback riding. That’s not what Demi needs to put her in check," the source added.

In order focus, she hasn't been in communication with anyone, but ex Wilmer Valderrama has been keeping up with her progress by checking in with her loved ones.

"Wilmer has been in touch with the family and has been checking in on Demi's status. The family is trying to make sure they eliminate all distractions and want her to be focusing on her health right now," another insider told E! News.

Everybody loves a comeback story, and we hope this is one!
