Following our extremely popular contest, 'HD Hottie Hysteria,' we've started a new feature in which we will highlight a top female star every day. The gorgeous female will come from a program that can be seen in gorgeous high-def that very day.The 24-year-old reality star, who was born in Crested Butte, Montana, got her first big break with some guest appearances on MTV's Laguna Beach, opposite friend Lauren Conrad.

She was later cast in the reality show, The Hills, which premiered in May 2006. The exposure quickly turned Heidi into an overnight reality show sensation, leading to a musical contract and one-time shots on such shows as The View and How I Met Your Mother.
Heidi has also been linked romantically to various celebrities, but eventually married her Hills co-star, Spencer Pratt; the duo last year released a new book called, How to Be Famous. There were reports that the couple was getting divorced, but apparently they are back together.
Heidi herself captured even more fame and fortune when she underwent several plastic surgeries to augment her breasts and other body parts. She also had a small part in Adam Sandler's Just Go For It and now she will star in a new reality series called Famous Food, which will air on VH1.
