Uma lets it all hang out!

Uma Thurman took a leisurely stroll around New York City on Wednesday, looking drastically different from her normally stunning-siren appearance.

Clad in a mismatched outfit of cropped black sweatpants, a bright red hat, and two oxford shirts tied to expose her stomach, the blonde beauty, 41, took her 9-year-old son, Levon, and his friends out for ice cream.

The makeup-less star, who carried a Louis Vuitton backpack and a pack of cigarettes fastened under her bra strap, smirked with a mini spoon hanging out of her mouth while photographers followed the group through the city's Upper West Side neighborhood.

But fans of the Kill Bill actress need not worry -- Thurman isn't exactly in a style rut: the night before she looked more like herself at a Calvin Klein event in NYC, where she was decked-out in a glam evening gown, sparkling jewels and undone curls.
