Wow! Kate Middleton stunned on Thursday evening when she and Prince William stepped out for the Royal Variety Performance at the London Palladium. The Duchess of Cambridge was rocking a tiny bump, which was only just noticeable in her elegant but sexy black lace Diane von Furstenberg gown. Middleton complemented the ravishing frock with a chic chignon, jewel-encrusted earrings, and a beaded clutch.

Kate and Wills were the guests of honor at the event, where Ellie Goulding, Bette Midler, Ed Sheeran, and Demi Lovato performed. The Duchess of Cambridge also came face-to-face with none other than the members of One Direction. And while many may find themselves tongue-tied when presented to the glowing soon-to-be mother of two, Harry Styles did not. "I said congratulations on the bump," he told reporters, according to People. "[Though] she didn't look bumpy."

If you want to recreate Middleton's stunning look, you're in luck—her DVF Zarita lace gown is still available on for $900. You can also buy a shorter version of the dress for $348 at
