Matt Lauer and Ann Curry led the group as the bride and groom, Prince William and Kate Middleton. Former anchor Meredith Vieira returned as Queen Elizabeth, with a few corgis in tow. She suffered an unfortunate hat and wig malfunction, but Vieira, being the pro she is, stayed in character.

Al Roker dressed as Prince Harry, Natalie Morales was given the honor of becoming sister-of-the-bride Pippa Middleton, and Savannah Guthrie did her best with Prince Charles.

Kathie Lee Gifford got to wear Princess Beatrice’s wacky hat, natch, with Hoda Kotb at her side as Princess Eugenie. Correspondent Sarah Haines dressed as pregnant wedding guest Victoria Beckham.

Stephanopoulos and Lara Spencer teamed up as Lady Gaga and her alter-ego, Jo Calderone., Bianna Golodryga was a tiny-bumped Beyonce, while Dan Harris, Sam Champion and Josh Elliot were the LMFAO boys.

In case you were wondering, Celebritology’s Jen Chaney suggested all of these costume ideas.
