demi lovato mother rehabJust months after Demi Lovato finished her rehab stint, the tough times don't seem to be letting up. The New York Post is reporting that the Disney-bred starlet recently called it quits with bad boy boyfriend, Wilmer Valderrama and is also dealing with some major family issues -- her mother, Dianna Hart de la Garza, headed to rehab.

"The age difference meant they were in completely different places in their lives," a source told the NY Post of Lovato's split from the 'That 70's Show' star, Valderrama, 31.

But a bad breakup seems to be the least of Lovato's recent woes. Her mother, who stood by her side during her stint in rehab -- and even got a matching 'Stay Strong' tattoo with her daughter -- entered rehab, herself.

"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," the source continued. "Now [that] Demi is strong again, her mom could take some time to deal with her own issues."
