Watch : Actor Lewis Pullman Expertly Dodges Kaia Gerber Question Amid Romance RumorsKaia Gerber admits she hasn't always been in model relationships. The 24-year-old detailed how the age gaps in her past romances sometimes created unhealthy dynamics within the relationships. "I used to be the opposite way where I would completely just change my personality, really, my values for someone," Kaia explained during the Oct. 1 episode of Jake Shane's Therapuss podcast. "I always dated people that were older than me, and so I was very willing to give up everything." For the supermodel—whose dating history includes Austin Butler, Pete Davidson and Jacob Elordi—she said sacrificing her own needs was a form of showing her affection.
