If Beyoncé's new album (which drops today) is a disappointment, no one told all of her famous friends who came out to see her sing last night in London.
After being the first female to headline the Glastonbury music festival this weekend, B continued her tour de force with a surprise album launch party and performance.
So who was front and center to see her sing her hits old and new, besides hubby Jay-Z?
In addition to performing new tunes from her album 4, including Girls (Run the World) and Best Thing I Never Had, the Grammy winner sang former hits like Single Ladies, Halo and Irreplaceable.
Bey also paid homage to other artists during the show.
"The highlight of evening came with a medley of covers from Queen's Bohemian Rhapsody and Kings of Leon's Sex on Fire," a partygoer tells me.
Guests toasted her with specialty Belvedere cocktails during the soiree.
We'll see how the album sells with the masses, but one thing's for certain: B's got plenty of celebrity fans!
