It's been a momentous year for Katie Holmes, who turns 34 today. To celebrate, she took Suri to the Metropolitan Museum of Art and then went for cupcakes at Sugar & Plumm, a delicious bakery on the Upper West Side that rightfully describes itself as "the purveyors of yumm." The weather in New York was particularly gross this afternoon, with that kind of misty cold precipitation that can't be fended off with an umbrella, so she wore boots, a navy wool Balenciaga coat, and carried Delvaux's Madame bag. Her 7 p.m. Dead Accounts curtain time on Broadway tonight could put a damper on dinner celebrations, but you never know. Take a gander at our Katie Holmes Look Book to appreciate her 34 years with us, below.
