Heidi Blair Pratt ( born September 15, 1986) is an American television personality. In 2004, she appeared in Laguna Beach: The Real Orange County, a former MTV reality television series in which her then-friend Lauren Conrad served as a main cast member. In 2006, Montag rose to fame as one of the original cast members of its spin-off The Hills, which chronicled the lives of Conrad, Montag, and their friends Audrina Patridge and Whitney Port.
Heidi Montag is back in the spotlight. The former star of The Hills has had a lot of work done on her body. Looking at these pictures, I would say it paid off! She looks great!
