The 2014 Grammy nominees for Best Pop Solo Performance come from a range of singers. Whether it's a former boy bander-turned-solo-success or a New Zealand newcomer, these artists represent the best pop music has to offer. Sara Bareilles, Lorde, Bruno Mars, Katy Perry and Justin Timberlake are all contenders for the honor. Who do you think should win the Grammy?

Remember how Katy Perry and her songwriting and production teams pretty much just did a cover of Sara Bareilles' 'Brave' with goofier lyrics and called it 'Roar?' So does Sara Bareilles. While she was neutral on the songs' similarities before, she's speaking out about it now.

Britney Spears isn't the only diva deserving of her very own Las Vegas residency. While Brit is locked up for two years in Sin City for her Piece of Me show, word has it that Katy Perry, who looked incredibly bored at Brit's opening gig, is eyeing her own residency.

Katy Perry has admitted that her image is superficial. That's honest of her, but it's true, since outward appearance is usually a fleeting thing. It's her music that's 100 percent real and authentic, and is that which will last and define her through and through.

Car crash love. Katy Perry explains that notion and concept in the six-minute, behind-the-scenes footage for her visually stunning 'Unconditionally' video.

Katy Perry looked lovely, with her hair slicked back off her face and wearing a strapless, iridescent dress, while she matched wits with British TV presenter Alan Carr. The pop diva and the 'Chatty Man' host drank hot toddies and noshed on sweets while they discussed the most, uh, intimate of topics.

You love who you love, regardless of gender, skin color or religion. That should be the governing principle of life in general -- but it's most certainly the case in the song and video for the John Mayer and Katy Perry duet 'Who You Love.'

Katy Perry followed her somewhat embarrassing performance at the NRJ Awards in France, which saw her lip-sync out of tune before flipping the switch to live, at the finale of British 'X Factor' (Dec. 15). She delivered a memorable performance of her sweeping song 'Unconditionally.'

Katy Perry has revealed why she and boyfriend John Mayer broke up last spring and the true reason she split with husband Russell Brand in her January 2014 Marie Claire cover. She looks pretty bangin', BTW!

Katy Perry has notched another mag cover, this time the January 2014 cover of Marie Claire, which is its first-ever Change Your Life issue. Perry would know a little something about that, wouldn't she?

Do Katy Perry and Niall Horan have something to tell us?

Katy Perry and John Mayer's duet 'Who You Love,' which appears on his album 'Paradise Valley,' will be the singer-songwriter's next single. Since it's a single, it has to have its own accompanying cover art and it features the couple posing in romantic fashion.
