Heidi Montag

Heidi's romantic life became a central storyline on The Hills. She dated Jordan Eubanks in 2005, breaking up in spring 2006. Soon after, she started dating Spencer Pratt, a former manager of Brody Jenner. The couple's engagement in May 2007 was called off during the season finale that December, but they reconciled and later married. In 2008, Montag described their relationship as "up and down" but said they loved each other. Her friendship with Conrad soured over rumors about a sex tape, though they reportedly ended their feud in October 2008.

Heidi has been open about her cosmetic procedures. In 2007, she admitted to breast augmentation, lip injections, and rhinoplasty. In November 2009, she underwent a dramatic transformation involving ten surgeries, including enlarged implants to a DDD cup, cheek augmentation, liposuction, and a buttock lift. She confessed she almost died from the procedures. In June 2011, she lost 27 pounds through a two-month workout regimen, bringing her weight to 103 lbs. By late 2013, she had her implants reduced back to a C cup.

Beyond reality TV, Heidi is a musician, podcaster, and TikTok star. In March 2008, she stated she was a Republican and planned to vote for John McCain in the 2008 election. Her stepbrother Eric O'Hara, an Iraq and Afghanistan veteran, died in a freak accident in March 2008. Heidi continues to be active on social media, with millions of followers across platforms, and she maintains an OnlyFans account.
