One of the many “instant celebrities” who achieved fame by virtue of the reality-television phenomenon that overtook Hollywood during the early years of the millennium, Heidi Montag attained stardom on The Hills (2006). This program — a spin-off of the earlier Laguna Beach (2004) — observed events from the lives of a couple of young L.A. socialites (Montag and Lauren Conrad) enduring the ups and downs of a melodramatic reality television life, with all of the inclusive breakups, ugly gossip, backbiting, friendship-destroying quarrels, and a whirlwind of other complications that such a lifestyle entails. Montag also made headlines (and a magazine cover or two) when she received extensive plastic surgery in the fall of 2007.
