This week on Twitter, celebs shared their candid moments of work and play. Nicole Richie played dress-up during her appearance on Watch What Happens Live, sporting a suit and tie just like host Andy Cohen. We also saw Alessandra Ambrosio showing off her baby bump in a chic neon sweater, Kate Upton trying out a voluminous new 'do, and Alexa Chung sharing some very eye-catching nail art. It's all inside this week's Twitter photo roundup.
Fun, Fashionable Twitter Pictures of the Week!
