At last year's MTV Video Music Awards, Katy Perry won the top prize -- Video of the Year -- for "Firework." However, she lost her fourth bid for Best Female Video, bested by Lady Gaga with "Born This Way."
Perry is back in contention this year with "Part of Me," the lead single from "Teenage Dreams: The Complete Confection," the re-release of her second studio album. The track was Perry's seventh number-one and mixes house, dance and pop to tell the tale of a young girl who stays strong and resolute after a breakup.
Perry's biggest competition is Rihanna who returns to this race for a third time, still looking for a win. This year she contends with "We Found Love" the lead single from the album "Talk that Talk." It too topped the charts and the video -- which depicts Rihanna as a thrill seeker in a dangerous relationship that devolves into addiction and abuse. Many found unsettling parallels with her real-life romance with Chris Brown that ended when he assaulted her.

Two-time champ Beyonce ("Crazy in Love," 2003: "Naughty Girl," 2004) is back with her seventh bid. She contends with "Love on Top" from her fourth studio album called, appropriately enough, "4." This uptempo R&B song showcased her vocal ability while the video highlighted her dance moves.
