Kate Middleton makes first public appearance since announcing pregnancy

The Duchess of Cambridge has recently made her first public appearance after announcing her second pregnancy on October 21.

Duchess Kate joined her husband Prince William to welcome the president of Singapore, BBC reported. The couple met Singapore's President Tony Tan and his wife in the presidential suite of London's Royal Garden Hotel.

The two couples then travelled to a ceremonial welcome on Horse Guards Parade in Whitehall, where a royal salute of 41 guns was fired in nearby Green Park upon their arrival. The Duchess of Cambridge also attended the Wildlife Photographer of the Year awards gala at the National History Museum later on.

The Duchess, who is about 12 weeks pregnant, has been suffering from extreme morning sickness which has forced her to miss recent engagements.
