And the boyfriend of the year award goes to Demi Lovato‘s beau, Wilmer Valderrama.

The “Skyscraper” singer, 22, got a sweet surprise from the 35-year-old actor when he appeared on stage Wednesday night at her benefit concert in West Hollywood.

Lovato performed her hit songs, including “Nightingale” and “Believe in Me,” and answered questions from fans to raise money for her Lovato Treatment Scholarship program. The only thing missing from the evening? Her boyfriend – or so she thought.

“My heart is broken that he couldn’t be here tonight,” she said – only to be interrupted by a cheering crowd and an unexpected entrance from Valderrama.

The “Really Don’t Care” songstress put her hands to her face in shock as the That ’70s Show alum leaned in for a kiss, which was captured in a video posted to YouTube.

“I just got off a plane from Toronto, and there’s like a million things to say,” Valderrama began.

“It’s been a long time since we’ve seen a role model like her,” he said, praising a teary-eyed Lovato for her progress and leadership.

“It’s been a long time to see somebody who has the courage to be exactly who she wants to be. If you’re going to take away anything from tonight, walk away with the understanding that, from today, life will get better,” he continued, then leading the crowd in singing “Happy Birthday” to toast Lovato’s third year of sobriety.

Lovato was noticeably tongue-tied and emotional after her boyfriend’s surprise gesture, stammering, “I don’t know what to say, so I’m going to go off-stage now!”

The pair have been dating on and off since 2010. Lovato has openly credited Valderrama with being her biggest supporter during her recovery from what her rep described as “physical and mental issues” back in 2010.

“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,” she wrote on Instagram on Sunday.

Lovato, who has publicly battled her issues, partnered with CAST Recovery in 2013 to create a special scholarship in honor of her father, who died after struggling with mental health and addiction issues.
