Heidi Montag

Reality TV personality turned pop singer Heidi Montag is best known as a regular cast member on the MTV show The Hills. Born in Colorado in 1986, Montag first came to the public's attention after she appeared in several episodes of season two of the MTV reality series Laguna Beach. Focused on the lives of several high-school students growing up in the elite California beach town of show's title, Laguna Beach was a hit and later spawned cast member Lauren Conrad's own 2006 post-high-school reality show, The Hills. Detailing Conrad's life in Los Angeles while attending the Fashion Institute of Design & Merchandising and working at Teen Vogue magazine, The Hills also showcased Montag, with whom Conrad shared an apartment at the time. Essentially the show's co-star, Montag dropped out of college and nabbed an internship at events promoter Bolthouse Productions — all of which was plot fodder for the series. However, it was Montag's relationship with cast member Spencer Pratt during season two of The Hills that drew the most attention.
