The 2013 American Music Awards were rife with amazing performances from Katy Perry, Ariana Grande, One Direction, Rihanna, Miley Cyrus, Justin Timberlake, Christina Aguilera, Pitbull featuring Kesha and more. And you can catch them all here!

For the 2013 American Music Awards, our favorite stars dressed to the nines. While some singers, like Ariana Grande, opted to go ultra-glam, others, like Katy Perry, had fun with the red carpet. (We're still obsessing over her book clutch.) Check out the photos of this year's best dressed celebs.

The elements factor into Katy Perry's 'Unconditionally' video. It looks like a period clip, mixed with some modern flourishes, like, you know, cars.

Katy Perry shared a 22-minute, behind-the-scenes feature from her 'ROAR' video. The making-of featurette is about three times as long as the actual official video, but you get a real sense of Perry's creative process and the joy she felt hanging out with the her co-stars aka wild animals.

Katy Perry's video for 'Unconditionally' is going to be epic! It explores topics like living life and loving without condition. We know that from the 42-second preview the singer shared.

Katy Perry has never been shy about admitting that she had a crush on a female friend at 15. Hello! That's what allegedly inspired her first smash hit 'I Kissed a Girl.' However, Perry never revealed to her friend that she was crushin'. Actually, it was more than crushin'. It was her first love.

Get ready for another epic Katy Perry awards show performance, Katycats!

Even though Katy Perry's first marriage ended in divorce after only 14 months, the singer's relationship with reformed Lothario John Mayer is going so well (despite that hiccup this past spring), that sources say it's pretty certain that they will get engaged.

Katy Perry became a human prism when she performed 'Unconditionally' at the 2013 EMAs (Nov. 10).

The 2013 EMAs, held in Amsterdam today (Nov. 10), saw celebs in a variety of different outfits. There were more cute, edgy dresses than there were fancy, couture gowns, since it's a fun, less formal event. The stars dressed accordingly and they all looked faboosh in their own, unique way.

So much for letting the light in! Katy Perry's chart-topping album 'Prism' has been labeled a biohazard in Australia.

Katy Perry continues to turn up on the cover of every magazine known to (wo)man. Her latest cover is the December 2013 issue of the Australian edition of Marie Claire.
