If you thought she was done becuase she went and had a baby, you were COMEPLETELY wrong. Beyonce stunned her first audience since the birth of Blue Ivy at the Revel Resorts in Atlantic City last night!

According to news & entertainment website Global Grind, Mrs. Carter performed a 27-song set full of voice, color, and power. Bey brought Sasha Fierce back from the dead and let her shine all night.

Beyonce performed a little of everything from her show-stopping career so far. She started with the up-tempo "End Of Time" (off the latest album, "4"), went through her biggest hits (including Crazy In Love, If I Were A Boy, Irreplaceable & more!!), then ended with the ladies' anthem "Single Ladies."

I'm sure EVERYONE in that audience left tired, but happy from such a huge night!!

Check out this video as a sneak peek of what you missed....
