April is turning out to be a very special month for Prince William and Kate Middleton.

The Palace also gave an update on Kate's health. In September, it was revealed that she was suffering from Hyperemisis Gravidarum (extreme morning sickness), just like her first pregnancy with Prince George, now 1.

"The Duchess of Cambridge continues to be affected by Hyperemisis Gravidarum, but her condition is steadily improving," the statement also reads.

Granted she's feeling well enough, Kate's first public appearance since the announcement of her second pregnancy is set for Tuesday, Oct. 21, when she and Prince William are scheduled to help welcome the President of Singapore Tony Tan Keng Yam to London on behalf of Queen Elizabeth. The couple will then travel with President and Mrs. Tan to the Horse Guards Parade, where the visiting dignitary will receive a ceremonial welcome. Kate is also scheduled to attend the Wildlife Photographer of The Year 2014 Awards Ceremony at the Natural History Museum on Tuesday.
