Can you see her baby bump?

(CBS News) The Duchess of Cambridge was out and about Tuesday morning. Kate Middleton, now four months pregnant, paid a visit to an addiction treatment center in London. She is a patron of this South London facility for women.

While she met with women recovering from alcohol and drug addiction, the big focus was on whether royal watchers could catch their first glimpse of the bump that may become a future King or Queen of England. The last time the Duchess was seen in public was Jan. 11 at the unveiling of her first official portrait.
