How did Learner Tien and Isabella Chhiv meet?

Learner Tien has largely kept details of his personal life private, so little is publicly known about how he and Chhiv first met or when their relationship began. The couple rarely shares details about their romance on social media. However, Tien offered a rare public show of support in 2026 after Princeton’s women’s tennis team captured a share of the Ivy League championship.

The Tigers secured a 4-1 victory in their final regular-season match, finishing with a strong 6-1 conference record. Following the achievement, Tien reposted the team’s “Ivy Champs” celebration on his Instagram Story, seemingly celebrating the accomplishment of his girlfriend, Isabella Chhiv, who was part of the championship-winning squad.

What does Isabella Chhiv do?

Chhiv is currently a student-athlete at Princeton University, where she competes for the Tigers women’s tennis team.

What is Isabella Chhiv’s net worth?
