"I'm kind of dating my first celebrity crush, so I feel pretty fortunate," Hough toldUs Weekly.
The 24-year-old actress and former Dancing with the Stars professional has been dating the 37-year-old American Idolhost for about two years.
Hough reportedly said one of the reasons the couple's relationship is so strong is because they are both highly motivated in their entertainment careers.
"I'm a very anxious person. If I'm not working, I go crazy," she told Glamour magazine, according to Us.
"I've been lucky in my career. But if I lost everything tomorrow -- and had no money -- I would somehow make it work. I have that survivor mentality because of a lot of stuff that went on in a previous life. I feel like I've had four lives."
Hough's current project is starring in Safe Haven, a romantic film based upon a Nicholas Sparks novel.
