A royal wedding wouldn't be complete without the queen. And who else could pull off the regal role but our own Meredith Vieira?
The former TODAY anchor surprised our hosts and audience members during our annual Halloween bash, this year themed to the royal wedding.
And of course Meredith played the Queen of England, granting her blessing to the marriage of Prince Williams (Matt) and Kate Middleton (Ann). They were joined by Prince Harry (Al), Pippa Middleton (Natalie), Prince Charles (Savannah) and Princesses Beatrice and Eugenie (Kathie Lee and Hoda). Check out images of the anchors here.
Since leaving TODAY, Meredith hasn't been far away. She joined "Rock Center with Brian Williams" as a correspondent. The show premieres tonight at 10 p.m.
