After a brief conversation, he got her phone number. Lonstein was still a senior in high school and would turn 18 at the end of that month. Seinfeld and Lonstein dated for approximately four years, until 1997. She transferred from George Washington University to UCLA, in part to be with him, and cited missing New York City and constant press coverage as reasons for the relationship ending.
