#KateMiddleton Is Back! #TheDuchessOfCambridge Makes First Royal Appearance & Debuts Baby Bump

On Tuesday, Kate Middleton made her first public appearance since announcing she is pregnant with her second child. The Duchess smiled and waved at well-wishers as she joined hubby #PrinceWilliam to welcome the president of Singapore, Tony Tan Keng Yam and his wife Mary, at London's Royal Garden Hotel.

Kate, who wore a grey Alexander McQueen coat and matching hat by Jane Taylor, looked well, despite having suffered from serious morning sickness for the first three months of her pregnancy.

After the brief meeting, Prince William and Kate traveled via carriage with #ThePresident and Mrs Tan to Horse Guards Parade, where they received a Ceremonial Welcome from #theQueen and the #DukeofEdinburgh.

The royals and their guests then continued to Buckingham Palace, taking part in a state carriage procession along the Mall. Prince William remained at the palace for lunch but Kate was not there.
