The only similarity between the It girls? Their The Row purses. Bieber followed Jenner's lead with a four-figure handbag of her own: specifically, the $4,400 Park Medium Woven Leather Tote in black.

Bieber, 28, wore a white tank top with baggy jeans and kitten heels sandals, while Jenner, 29, was dressed in sandals and a short-sleeved gray maxi dress. Smiling mom-of-one Bieber held onto an iced coffee as she made her way into the store, while model Jenner had a large brown tote bag on her shoulder.
