Heidi Montag (born September 15, 1986) is an American reality television personality, fashion designer, and pop singer. Montag, along with her boyfriend Spencer Pratt, have made a joint fortune of $3 million in the last two years alone thanks to TV salaries, club appearances, photo shoots, and business deals. In the summer of 2005, MTV began filming the lives of Laguna Beach cast member Lauren Conrad and her college friends for her spin-off reality show, The Hills. Montag's reality TV career began with a few appearances on season two of MTV's Laguna Beach. Montag's friendship with Conrad led to a featured role in The Hills, which premiered on May 31, 2006. Montag was featured in the series sharing an apartment with Conrad while studying at the Fashion Institute of Design & Merchandising in Los Angeles. Montag left the Fashion Institute in fall of 2005 when she was hired at Bolthouse Productions. According to Montag, she dropped out because she "did not find the school challenging". Within two years, Montag was promoted to event planner at Bolthouse, before being fired. Montag appeared in every episode of seasons one and two of The Hills, and appeared in season three, which aired on MTV on August 13, 2007. In the summer of 2006, Montag started dating fellow Hills cast member Spencer Pratt, a former manager of Brody Jenner. Season 2 of The Hills (which aired from January through April 2007) focused on Montag's relationship with Pratt and its effect on her friendships with Conrad and fellow Hills cast member Audrina Patridge. On the Season 2 finale, Montag moved out of her apartment with Conrad to live with Pratt.
