Beyoncé took the world by surprise when she released her fifth studio album without warning on Thursday night. It has been reported that the self-titled project will debut at No. 1 on next week's Billboard 200. It sold over 430,000 digital units in 24 hours of its release and it is estimated to sell 600,000 before the chart's deadline. If she makes that number, it will be her biggest debut week in her career since B'Day, which kicked off its first week with 541,000 in sales back in September 2006.

Congratulations, King B. You deserve a treat.

The Mrs. Carter World Tour hit Chicago's United Center last night, where she performed the track "XO" for the first time ever. Watch a video from the concert below.
