Demi Lovato: Break-up with Wilmer Valderrama, mom in rehab
Lovato and Valderrama allegedly split because their 13-year age difference became a significant obstacle in the relationship. The pair has been dating since Lovato's release from her own rehab stint in January.
De la Garza, who is also mom to "Desperate Housewives" star Madison de la Garza, supported Lovato throughout her time in rehab. According to the Post, she was waiting for Lovato to stabilize so that she could take some time to herself and work on her own issues.
