AceShowbiz - Beyonce Knowles was reportedly recovering from a surgery prior to her much-talked-about performance in Dubai. The R&B diva is said to have recently undergone a foot surgery ahead of the private show.

Report of Bey's alleged recent surgery surfaces after photos and footage leaked from her concert at The Royal Atlantis. Raving about her performance, cultural critic and author Gerrick Kennedy tweeted on Saturday, January 21, "BEYLANTIS was quite the unexpected show. That voice is just gets better and better. Mama was doing her good singing."

"Mind-blowing to see her and Blue Ivy perform together. Even more in awe to hear she did this after foot surgery," the critic claimed, before adding, "It's unclear what injury led Bey to the operating table, but it's good to know she's doing better."

Beyonce was billed to perform at The Royal Atlantis hotel's opening on Saturday, local time. For the show, the Grammy winner rocked a feathery, bright yellow ensemble. She brought along her daughter Blue Ivy Carter onstage to perform their collaboration "Brown Skin Girl". Kicking off her performance, Beyonce exclaimed, "Where are all my brown skin girls?" She then gave a shout-out to her eldest child, "Give it up for my baby, my brown skin girl, Miss Blue Ivy Carter."

She then informed the audience that her husband Jay-Z, their twins Rumi and Sir as well as her parents Tina Knowles-Lawson and Mathew Knowles were also there to watch her perform. "My beautiful children are here to see their mom perform," she declared.

During the nearly 75-minute show, Beyonce belted out a cover of Etta James' "At Last" before delivering rendition of some of her hits, including "Beautiful Liar", "Halo" and "Crazy in Love". She was reportedly paid $24 for her first live show in almost five years.

Kendall Jenner, Rebel Wilson, Ellen Pompeo, Winston Duke, Letitia Wright, Liam Payne, Chloe x Halle and Bar Refaeli were also celebrities attending the show. Also performing at the new ultra-luxury resort were Swedish House Mafia.
