Julianne Hough running Miami Beach blonde shorts

Julianne Hough is super serious about her fitness and it pays off!

The superhot dancer-singer-actress did some beach jogging in Miami Friday while on break from shooting Rock of Ages with Tom Cruise, Russell Brand, Alec Baldwin and others.

Hough just got a visit from boyfriend Ryan Seacrest and the two enjoyed a few lunches and dinners together at some South Beach hotspots but now it's back to work for both of them!
