Photos of Jay-Z, Taylor Momsen, Michelle Trachtenberg, Zach Braff at TopShop Balthazar Launch Party

TopMen and Women Celebrate Topshop Opening in the US

There was an eclectic crowd at Balthazar last night in NYC to celebrate first Topshop in the states, which opens in Manhattan tomorrow. Jay-Z — whose next project may involve Amy Winehouse — posed with Zach Braff while Taylor Momsen stood out in a hot pink skirt on the black carpet. Michelle Trachtenberg shined in her sequin dress and Emma Roberts stayed a little more covered up. Kate Moss isn't there to join in the festivities yet, but she's expected on Thursday when the store finally opens its doors.
