If we weren't already watching the throne for Beyonce's hubby, Jay-Z, we certainly are now for Queen B.

The 'Love on Top' songstress released a full promo for her Mrs. Carter Show world tour that features Bey as a Marie Antoinette look-alilke with a harem of gentlemanly backup dancers and a joker DJ. The clip shows Beyonce lurching forward (and backward) in slow motion in an impeccable 18th century period costume. We really hope her wardrobe for the tour follows this motif because those duds are seriously fabulous.

The music in the two minute promo is a haunting little tune, but gives us no indication as to whether it's a Beyonce original -- though we're betting is might be featured on her upcoming album, even if just an interlude.

The Mrs. Carter Show world tour will hit 41 cities in the U.S., Canada and Europe beginning in April and wrapping up in August at (where else?) the Barclays Center in Brooklyn, N.Y.
