Demi Lovato and her boyfriend praised each on Instagram, according to a report from Page Six. In the said post, the "Skyscraper" singer claimed that Wilmer Valderrama helped her stay sober for the past three years.

The 35-year-old star of "That '70s Show" posted a tribute last Sunday to celebrate his girlfriend's sobriety anniversary.

"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," Wilmer Valderrama wrote.

"And I'm sure glad you did... I knew then the woman you've become now."

"I am proud and honored to be front row to see the world you are about to change. I love you," he posted.

Demi Lovato then thanked her boyfriend by uploading a black and white Instagram photo of them in a loving kiss.

"I wish I could put into words how grateful I am for this man right here. My love has grown to a level that words could never possibly express how much this man completes me," Demi Lovato captioned the image.

"He's loved me the way I never thought I deserved to be loved and with this day making 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," she wrote.

According to a report from E!Online, the pair has long been hounded with engagement rumors.

The rumors began a year ago after the "Camp Rock" lead actress uploaded a selfie on Twitter that showed a ring on her wedding finger.

Wilmer Valderamma addressed the rumors at Unite4Good's Unite4Humanity gala event at the Beverly Hilton hotel last month.

"We're not engaged," Wilmer Valderrama clarified, reported by E!Online. 

"But you know it's something that I definitely look forward to in the future. We'll see."

"You know, who knows?" the actor teased.
