Kirsten, is the eldest daughter of real estate developer Caleb Nichol and the older sister of Hailey Nichol and older half-sister of Lindsay Gardner. She married husband Sandy Cohen sometime during her rebellious twenties (she states that when they fell in love, she "lived in a mail truck and stank of patchouli"). Since marrying Sandy and giving birth to their son Seth, Kirsten joined her father at the Newport Group, becoming somewhat of a workaholic. Unlike her husband, Kirsten is conservative.

Life before Season 1 Edit

Kirsten dated Jimmy Cooper during high school but broke up with him when she was admitted to Berkeley University - at least, that was her excuse for the break-up. The truth was that she was pregnant but she decided to abort (secret that she decided never to reveal to Jimmy, but instead to reveal it to Sandy, but only years later).

While Sandy is away with the boys in Miami, she invites Carter over and they share a passionate kiss before he decides to leave town. After Carter leaves, Kirsten's drinking problem becomes worse. She drives drunk and gets into a severe car accident, which leaves her undamaged. When her father, Caleb, tries to talk to her about her drinking issue, Kirsten says extremely rude things. This is the last time she sees her father. At his funeral, Kirsten makes a scene by drinking far too much and screaming at Sandy in the middle of the reception.
