The 34-year-old beauty flaunted her super-slim post-baby body at the Glamour 2014 Women Of The Year Awards in New York City on Monday.
The former first daughter looked beautiful in a sleeveless, black form-fitting printed dress, which she paired with metallic pumps, tousled waves and minimal makeup.
Chelsea welcomed a baby girl with husband Marc Mezvinsky on September 26. "Marc and I are full of love, awe and gratitude as we celebrate the birth of our daughter, Charlotte Clinton Mezvinsky," she wrote on Twitter.
Proud grandmother Hillary Clinton shared an adorable photo of the new addition. "@BillClinton and I are over the moon to be grandparents! One of the happiest moments of our life," she captioned the pic.
We can't wait to see more photos of Charlotte!
