CNN is reporting that Kelly checked into a treatment facility in Los Angeles this week. She passed away in her sleep on Wednesday night.
"Lisa had voluntarily checked herself into a treatment facility early this week where she was battling the addiction problems that have plagued her these past few years," said Kelly's agent Craig Wyckoff.
Wyckoff said when he last spoke to her on Monday, she was "hopeful and confident" as she looked forward to getting her life together.
"(Wednesday) night she lost the battle," Wyckoff said.
Wyckoff said no cause of death has been reported and no death certificate has been issued.
