Kate Middleton made her first appearance since the announcement of her second baby with Prince William.

Middleton together with husband Prince William met with the President of Singapore and his wife Mary wearing a structured and very elegant gray Alexander McQueen coat coupled with a sharp Jane Taylor hat at the London's Royal Garden Hotel. They went to the Horse Guards Palace for an official welcome after that.

Middleton went to the Natural History Museum in London, England to present the Young Wildlife Photographer of the Year Award on Tuesday, Oct. 21.

The 32-year old Duchess of Cambridge, a patron of the museum, and upon her grand arrival was presented with a posy by Sophie Milner, 13, daughter of Dr. Jonathan Milner, a trustee of the museum.

She was then joined by British TV naturalist Sir David Attenborough to present the awards after meeting the finalists and viewing their work.

She wore a stunning baby blue tight fit Jenny Packham long gown to the event. Whether she intended to wear a baby blue gown to formally announce her pregnancy or it was purely coincidental is unknown.

Her baby bump peeked through gown which features a slightly revealing long slit showcasing a skirt underneath.

Meanwhile, Middleton reportedly suffers from hyperemesis gravidarium, which causes severe nausea and vomiting as well as weight loss. The condition is also common to mothers bearing more than one baby, that's why rumors are up and about right now that the Duchess of Cambridge may be having royal twins.

Middleton had to spend the past weeks resting while trying to gain back the weight she had lost.

According to Latin Times, the Royal Family announced on Monday that their second baby will be due in April next year. There are no reports of the sex of the baby. However, a British online betting company, Ladbrokes shows that there are many bets that it's a girl.
