Wilmer Valderrama praises girlfriend Lovato's sober anniversary

Actor Wilmer Valderrama has saluted his girlfriend Demi Lovato with a touching tribute in honor of the third anniversary of her sobriety.

The Skyscraper hitmaker completed a stay in a rehab facility to treat her eating disorder and drug and alcohol addiction three years ago, and applauding the milestone, her longtime beau took to Instagram.com over the weekend (15Mar15) to praise her impressive achievement.

He wrote, "Today, we lay another stone together. It is now 3 years since you said: I am more important then any past, demon, disorder or addiction. Where you decided that YOUR life was worth living while loving yourself. And I’m sure glad you did.

"I knew then the woman you've become now. I am proud and honor (sic) to be front row to see the world you are about to change. I love you Demi."
