20.Jai Ho! (You Are My Destiny) by A R Rahman & Pussycat Dolls featuring Nicole Scherzinger The video is one of their best, I love it, Nicole looks beautiful during the solo shots, and the choreography is amazing.
19.3 by Britney Spears Some might think that the video is bad, but it's far from that. This is the best Brit looked in a long time (she just needs longer bangs) and the choreography is good. Simple and hot.
18.Party In The U.S.A. by Miley Cyrus The video is simple and great and Miley never EVER so far looked this hot. Disney queen ******** on your faves.
17.Russian Roulette by Rihanna She's the only artist with 2 videos on the list. The video is so dramatic and intense. Her hair looks awful, but she looks hot. The part where she gets hit by a car and the shots in the water are epic.
16.Knock You Down by Keri Hilson featuring Kanye West & Ne-Yo I think the story or the video is just OK, but Keri looks great and the scenes on the bad and hot as hell. Some scenes seem amateurish (when Kanye breaks and stuff), but the video is still good.
15.Don't Forget by Demi Lovato This has to be her best video. She looks more beautiful than ever, the video and the rain fit the song perfectly. The performance when the song breaks down is amazing.
14.Paparazzi by Lady GaGa GaGa's first and last appearance on the list. Her 2nd best video after "Poker Face". It has a great storyline and it fits the song.
13.22 by Lily Allen One of the best videos of the year and her best video. It has a amazing storyline and Lily's act is amazing. And the bad version of her looks bad as hell.
12.Please Don't Leave Me by P!nk Only P!nk can make such a great, fun and morbid video that is so her. The scenes where the guy falls down and the last scene with the axe are epic.
11.Happy by Leona Lewis Her best video since the UK version of "Bleeding Love" and probably her best video. It's so sad, simple and she never looked this beautiful in a video. The ending makes me wanna cry.
