She is the current wife of Eddie De La Garza and former wife of Patrick Lovato. According to Demi in an interview with TVGuide.com, it was Dianna who "brought the singing" out of her. In the early 1980's, Dianna was a professional cheerleader for the National Football League's Dallas Cowboys. After performing several times, Dianna decided to pursue a singing career, which led her husband Patrick to divorce her. As Patrick said himself to Star magazine, they divorced because their long-distance relationship was not working.
