Sophie Winkleman as Zoey Hyde-Tottingham-Pierce
Zoey was the gorgeous British ex-girlfriend that Walden was serious about after his divorce from Bridget. When they first went out, Walden would cry to her about how depressed he was that he and Bridget were over. She wanted to end things, but he insisted that things were over with him and his ex-wife. He helped get her daughter into the private school she wanted to attend, and they end up consummating the relationship on his private jet. After dating for two seasons, Zoey rejected his marriage proposal. Walden then discovered that Zoey had been dating another man and decided to seek revenge.
