Duchess Of Cambridge Goes Glam In Sexy Gown (PHOTOS)

It seems as if the night brings out the best in the Duchess of Cambridge!

On Tuesday evening, Kate Middleton attended the 50th Wildlife Photographer of the Year competition at the Natural History Museum in London sporting a sexy blue Jenny Packham gown.

The pregnant Duchess, who has been suffering severe morning sickness for the past two months, flaunted the tiniest of baby bumps (you can barely see it!) in the red carpet-sweeping gown that featured a slit up to there, long sleeves and a modest v-neck. Kate's signature wavy blowout, cream sandals and a matching snakeskin clutch completed the glamourous ensemble.

This is Kate's second appearance since the announcement that she was pregnant with her and Prince William's second child, and the second time the public has seen her since August, when the 32-year-old visited the Tower of London's 'Blood Swept Lands and Seas of Red' poppy installation.

Earlier on Tuesday, Prince George's mum welcomed the president of Singapore and his wife Mary for a historic visit to the UK and wowed in a chic grey Alexander McQueen coat and Jane Taylor hat.

Kate and William's child is due in April, 2015.

We missed Kate's style!
