Beyoncé pens the ultimate kiss off in the video for “Best Thing I Never Had,” the second single from her No. 1 album 4. The Diane Martel-directed clip flashes back to a teenage B attending the prom with her high school sweetheart, who leaves her on the dance floor and flirts with another girl. But years later, it’s B who gets the last laugh when she walks down the aisle with her new husband. Don’t miss the fairytale ending.
