On Saturday night, a handful of the world's biggest pop stars (Taylor Swift, Ariana Grande, Gwen Stefani, Iggy Azalea, Maroon 5 and more) descended upon Madison Square Garden for the annual Z100 Jungle Ball, a rapid-fire concert showcasing the year's biggest Top 40 hits.
"Birthday girl Taylor Swift was the undisputed empress," Rob Sheffield wrote is his report from the event, "especially in the final minutes as the clock ticked down to midnight. If you thought there was any chance that Taylor was going to surrender the stage before midnight and miss the opportunity to turn the entire event into her own personal birthday bash, you've probably never heard of Taylor Swift. This girl likes to make a scene, which is why she rules the pop world."
