Prince William and Duchess Kate welcomes second baby in April 2015

The Duke and Duchess of Cambridge Prince William and his wife Kate announced today that their baby, the 4th in line to the British throne is due in April 2014.

The couple who did not reveal if the baby being expected is going to be a boy or a girl ruled out twins.  The couple got married on April 29th, 2011.

The pregnancy was announced September 8, and the princess had to cancel several appointments due to severe hyperemesis gravidarum (severe morning sickness).

The Duchess returned to normal official work on Tuesday welcoming the President of Singapore and his wife with the Duke for their state visit to the Queen.

The baby will be fourth in line to the British throne after grandfather Prince Charles, father Prince William and big brother George. The baby will be the second for the royal couple, joining 1-year-old George
