VIDEO : Madonna and Katy Perry Have Loads of Fun at the Met Gala

Madonna may have made one of Katy Perry's teenage dreams come true. On Monday, the pop star got to walk the glamorous red carpet with the iconic one-woman show. The ladies could not stop giggling and smiling as they posed for snaps and gave fun interviews, and their antics got even more unpredictable as the night continued. At one point, Madonna and Katy linked up with fellow diva Lady Gaga, with whom Madonna has had a headline-grabbing feud. The ladies put it all behind them for night, though, and Katy even joked about a collaboration between the three.??
