Julianne Hough keeps pup Lexi close backstage during the Country Stampede 2009 at Tuttle Creek State Park last month in Manhattan, Kansas.

The two-time Dancing With The Stars champion celebrates her 21st birthday today!

Julianne recently caught up with Teen Vogue magazine to chat about her upcoming role in Footloose. She shared, “After I’m done touring I will be working on my album, which is a lot more mature and has edgy, rock, sound. Footloose is also in progress, and we have just started the scheduling for that. I am really excited because everyone knows how great the original was!”
