Pregnant Kate Middleton Shows Off a Whole Lotta Leg

The Duchess of Cambridge sure knows how to sizzle in maternity wear. PHOTOS: Kate Middleton Debuts Tiny Baby Bump In her first official red carpet appearance since announcing her second pregnancy, Kate Middleton attended the 50th Wildlife Photographer of the Year competition at London's Natural History Museum on Tuesday. And while she could have worn any formal piece of her choosing, like the conservative Alexander McQueen gray suit-dress she wore to meet the President of the Republic of Singapore earlier in the day, the 32-year-old chose an outfit that flaunted more of her enviable royal assets. No longer cooped up in her bed while battling severe morning sickness, Middleton strutted her stuff in a dress that proudly revealed a tiny baby bump, along with her signature lean legs. The gown, created by her favorite designer and fellow Brit Jenny Packham, was a light blue floor-sweeping number that featured a peekaboo skirt with a long slit down the side, and it paired nicely her with strappy ivory open-toe stilettos. And, as expected, the royal’s mane was perfectly glossy and downright swoon-worthy. READ: How to Get Lean Legs Like Kate Middleton Us Weekly added that Middleton, a patron of the museum, was joined by British TV naturalist Sir David Attenborough to present the awards after meeting the finalists and viewing their work. Unfortunately for Attenborough, Middleton easily stole the spotlight from the duo. Middleton, along with husband Prince William, will welcome their second child in April 2015. The baby will be a younger brother or sister to their first child, 14-month-old Prince George. Check out the photos from the Natural History Museum's event below:
