This might be the sweetest video we have seen all week! 5-year-old Kai Langer, aka the most adorable little kid on the planet, stopped by the 'Ellen DeGeneres Show' to chat with the host and show off his rendition of Katy Perry's anthem, 'Roar.'

Katy Perry is now the proud owner of an adorable dog, she announced via a cute-beyond-words Instagram pic of her new pet.

I love Katy Perry. Her songs always have a great hook. They're really catchy -- there's something appealing that speaks to me in each one. Plus, I love to perform the acoustic versions with my own guitar. In fact, her song, "Thinking of You" was one of the first sings I ever learned on guitar!

A few months ago, an insider said that a Katy Perry and John Mayer engagement was inevitable and that they were on that path. Did they finally become betrothed?

If Santa is making a list and checking it twice to find out who has been naughty and who has been nice this Christmas season, well, Rihanna will certainly be on the former list. She posted some, uh, holiday merriment pics on Instagram and a handful of 'em will make the already red-cheeked St. Nick blush even more.

It is with a heavy heart that we report that Olivia Wise, the 16-year-old with an inoperable, aggressive brain tumor who previously covered Katy Perry's 'ROAR' in a recording studio has died.

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 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.

Katy Perry doesn't want to make out with Drake. She wants to make out to Drake. His music, that is!

Britney Spears and Katy Perry are forever linked by 'The Smurfs 2' -- and not just because Brit Brit sings 'Ooh La La' (the ending credits song) and Perry voices Smurfette in the flick. Perry actually sang backup on 'Ooh La La,' too! True story.

After two splits in under a year, Katy Perry thinks the third time with John Mayer will be the charm. To help hedge her bets a little, though, she's established some ground rules that we're sure he'll follow for a week or so.

Now that Katy Perry and John Mayer are back on again, the 'Fireworks' songstress is laying down some ground rules for the 'Paper Doll' singer-songwriter. If he wants to date Perry again, he's got to follow some dang guidelines!
