Celebrities can be fans, too.

In a new interview with EW, Abigail Breslin explains that she was once obsessed with Zac Efron, though their first meeting while working on New Year’s Eve did not go well.

Although Breslin and Efron didn’t work together on the movie where they played uncle and niece (“which I thought would be a real cute story to tell our kids one day”), they ran into each other while recording automated dialogue replacement. Breslin describes her outfit as “sweatpants and a dinosaur T-shirt and my hair was in a ponytail and I had Sketchers on — I looked like I was 8 years old.” As a result, when Efron said hello, Breslin hid in the bathroom for 25 minutes.

“Great, now Zac Efron thinks I have stomach issues,” Breslin says. “Beautiful. So glad this happened.”
