About Heidi Montag
Heidi Blair Pratt is an American reality television personality and singer. In 2006, Montag came to prominence after being cast in the MTV reality television series The Hills. The show chronicled the personal and professional lives of Lauren Conrad, Montag, and friends Audrina Patridge and Whitney Port. During its production, she briefly attended the Fashion Institute of Design & Merchandising and was "employed" by event planning company Bolthouse Productions.
