Beyonce is back. The pop star gave her first post-baby concert last night at the new Atlantic City venue Revel.

Before hopping on stage Beyonce told the NY Post:

"It is exciting. I’m a little nervous, though… It’s like going back to my old job. It’s a little strange. But it’s important that you don’t lose yourself and you still have your own passions. I’m back to work. I’m back to business."

Beyonce will get rid of all those nervous feelings this weekend as she’s scheduled to play three more shows at the Revel. According to her husband Jay-Z, Beyonce’s performance last night was one of the best of her career.

Jay Z said:

"I’m gonna say this and then I’m gonna end mine. BEYONCE is the best performer in the world. Period.

Entertainment blogger Miss Jia agreed:

"I swear I’ve just witnessed the best concert ever."

Beyonce worked her way through an impressive list of songs. She sang newer material like "Halo" and old classics like Destiny’s Child’s "Jumpin’ Jumpin’" Beyonce also sang a rendition of "I Will Always Love You," and Lauryn Hill’s "Ex-Factor."
