Newly-Single Demi Lovato’s Mama Drama

She’s been on a long road to recovery from her plethora of personal problems, and it seems that Demi Lovato's life continues to be complicated.

According to FOX News, the “Sonny with a Chance” chick’s mom Dianna Hart de la Garza has checked into rehab for her own issues.

An insider told press, "It has been a tough year for Demi, and her mom has been a constant source of support. But fame has also taken its toll on her family. Now [that] Demi is strong again, her mom could take some time to deal with her own issues."

Additionally, 18-year-old Demi has also called it quits with Wilmer Valderrama (31). "The age difference meant they were in completely different places in their lives," said a source.
