Once the sweet and bubbly BFF of Lauren Conrad on MTV's The Hills, Heidi Montag decided to break away from LC and start some drama of her own with her bad boy boyfriend Spencer Pratt. By the end of season 2, Lauren and Heidi were no longer on speaking terms, but her friendship with the reality star wasn't the only thing that changed. Heidi went under the knife and sported a new nose and bigger breasts, landing her on the covers of Maxim and Playboy. In 2009, despite his bad reputation, Heidi married Spencer and the troublemaker couple became known as Speidi. In 2010, Heidi admitted to having 10 plastic surgery procedures done in one day and revealed her drastic new look to the public. Although filing for divorce, Speidi is still together, but haven't stirred up much drama since The Hills came to an end in 2010.
