Brad Pitt was there to attend a sixth birthday party thrown by rocker pal Chris Cornell for his daughter Toni, who is best friends with Zahara.
A source tells the magazine, "It was just Brad, Zahara, the Cornell family and one other little girl. The three girls were inseparable."
And even though the store is designed to give little girls the experience of their life, Brad Pitt appeared to enjoy his visit.
The source adds, "Brad went around the store holding Zahara's hand and looking at the dolls and dresses. The staff explained the dolls' histories, and Brad and Z were just lapping it up. Brad was very attentive to Zahara. He's a great dad."
