"I thought it was extremely brave of a pop star in the industry to come out and talk about that," the 23-year-old singer said of the alleged mental, physical, verbal and sexual abuse Kesha suffered working with producer Lukasz "Dr. Luke" Gottwald.
She added, "I do believe it's very fucked up that he's not letting her go, aside from all of the other stuff."
A judge denied a motion in February that would have released Kesha from her Sony contract, ruling that she was free to work with another producer for the label.
Lovato tweeted her support for Kesha after the disappointing ruling, saying it was "Frustrating to see women come forward with their past only to be shot down, not believed & disrespected for their bravery in taking action."
The singer later got herself in trouble when she appeared to undermine Taylor Swift's $250,000 donation to Kesha when she tweeted, "Take something to Capitol Hill or actually speak out about something and then I'll be impressed."
No matter who the tweet was directed at, Lovato appears to shake it off in Latina magazine.
"I think women artists shouldn't compete -- we have to support each other," Lovato said.
