During a little Q&A with fans, Demi explained that Wilmer wasn't able to be there, saying, "My heart is broken that he couldn't be here tonight." She wasn't heartbroken for long, as he took to the stage while she said, "Stop" in disbelief. Check out that smile! And then the tears. And then they kissed.
Wilmer told the crowd: "So I just got off a plane from Toronto. And there's like a million things to say...it's been a long time since we've seen a role model like her. It's been a long time to see somebody who has the courage to be exactly who she wants to be. And if you're going to take away anything from tonight, walk away with the understanding that, from today, life will get better."
He also got the audience to sing "Happy Birthday" to Demi, who celebrated her third "birthday" of sobriety earlier this week.
