Just a week after being spotted sitting front row together at the Calvin Klein Men's Collection fashion show in New York, Zac Efron and Joe Jonas both headed to Fred Segal to get in a little shopping on a rainy Friday afternoon.

It's unclear if they actually bumped into each other in the dressing room at the famous West Hollywood boutique, but the teen heartthrobs left separately.
