Kate Middleton shows off baby bump in a Disney princess-esque dress

Cinderella vibes anyone?

Kate and William attended the Royal Variety Performance at London's Palladium Theatre last night, and we just can't get over Kate's dress. The Duchess, who is pregnant with the couple's third child, wore a sparkling blue dress, designed by Jenny Packham, that had a sheer overlay embellished with shimmering crystals, stars and flowers. Dreamy, right? Kate teamed the dress with a pair of sparkly Oscar de la Renta heels completed the outfit. We have to say, this is one of our favourite Kate Middleton outfits. Images: Getty
