The singer, who is pregnant with twins, WILL headline the festival in 2018 -- so at least the Beyhivé has that!
In a statement to The Associated Press on Thursday, Bey's Parkwood Entertainment and festival producer Goldenvoice said:
At The 100th Royal Variety Show the songstresses sang an old favorite, The Promise, and they reminded us just how much we long the song's vintage feel.
The queen must already be in a great mood after hearing she will be a great-grandmother and we bet the girls only added to her joy!
Ch-ch-check out the ladies light the stage on fire(above)!!
