Demi Lovato is officially three years sober and more in love than ever!
The "Skyscrapers" singer opened up about her major milestone via Instagram on Sunday by posting a sweet pic kissing longtime boyfriend Wilmer Valderrama, in addition to sharing a very loving message for the "That '70s Show" alum.
"I wish I could put into words how grateful I am for this man right here. But my love has grown to a level that words could never possibly express how much this man completes me," the pop star captioned the candid snap.
"He's loved me the way I never thought I deserved to be loved and with this day marking my 3rd year sober... After sharing my ups, putting up with my downs and supporting my recovery... he still never takes credit and I want the world to know how incredible his soul is. I really wouldn't be alive today without him. I love you Wilmer," Demi added.
Lovato -- who's publicly struggled with eating disorders -- likewise took to Twitter to thank all of her fans for their fellow support.
I'm still catching up to texts and congrats tweets... Thank everyone who has supported my journey. I never knew sobriety was possible for me
