Beyonce Knowles is giving a treat to those who didn't make it into her four-night concert series in Atlantic City, New Jersey. On Sunday, May 27, the "Halo" singer uploaded an exclusive video on her official site that captures her busting her moves to "End of Time" in the opening number of her Revel Resort show.

The clip is 90 seconds long and displays Beyonce kicking off the performance by appearing solo in silhouette. Wearing a glimmering silver dress by Ralph & Russo and a pair of hot pink shoes, the songstress wife of Jay-Z then stormed the stage inside Ovation Hall along with her backup dancers and Les Twins.

During the comeback shows, Beyonce entertained her fans with such hits as "Crazy In Love", ''Get Me Bodied", "Party", "Baby Boy", "Single Ladies (Put a Ring on It)" and "Run the World (Girls)". The 30-year-old also delivered a rousing rendition of "Resentment" as well as belted "1+1" while sitting on top of a piano.

Beyonce also paid a tribute to late singers Whitney Houston and Donna Summer. She sang a verse of Houston's "I Will Always Love You" and gave Summer a shout-out with her "Naughty Girl" performance that samples the late singer's hit "Love to Love You Baby". Additionally, she covered Lauryn Hill's classic, "Ex Factor."

Beyonce's Saturday, May 26 show saw First Lady Michelle Obama and her daughters Sasha and Malia among the attendees. Other stars showing their support included The-Dream, Terrence J, Kevin Hart, Angie Martinez, fashion designer Vera Wang, Governor Christie, and Hollywood couple Will Smith and Jada Pinkett Smith.

The four-night concert was kicked off Friday, May 25 and will come to a close on Sunday, May 28. It marked Beyonce's first since giving birth to daughter Blue Ivy Carter in January. During her Saturday performance, she joked with the crowd, "Y'all don't know how hard I had to work. I had to lose 60 pounds! They had me eating lettuce."
