Demi Lovato and Friends Are Setting the Record Straight on Dancing With the Devil

Matthew and Demi first met through his So Random! costar Tiffany Thornton back in 2011. "I love Demi with all my heart and all my soul. She's like one of my favorite people I've ever met," Matthew said of their friendship. He's been part of her inner-circle ever since, with Demi thanking him in a 2019 Instagram post "for never leaving me in my darkest moments." Along with Demi's most recent documentary, Matthew appeared in the music videos for her songs "Tell Me You Love Me," "Sorry Not Sorry," "Really Don't Care," and "I Love Me."
