Bundled up for the chilly temps in New York City this weekend, Brad Pitt and longtime partner Angelina Jolie did some holiday shopping with their youngest kids, twins Knox and Vivienne -- who turned 2 in July -- in tow.

Jolie and family are in town after spending Thanksgiving in Paris because Monday is the New York premiere of her latest film, 'The Tourist,' co-starring Johnny Depp.

The famous foursome -- Pitt, toting their son, and Jolie, carrying their daughter -- were spotted by photographers and starstruck passersby as they exited Lee's Art Shop in midtown Manhattan.

It isn't the first time the jet-setting couple have patronized the neighborhood institution, which stocks stationery, home decor, lighting and art supplies; they've previously been seen shopping for gifts (Jolie is reportedly crazy about celebrating Christmas) at Lee's with all four of their older children in the past.
