Katy Perry has finally and officially confirmed what the world knows and is painfully obvious -- that she and BF John Mayer have split.

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.'

You don't want to mess with Lily Allen. In her bold new music video for 'Sheezus,' the title track off of her upcoming album, the outspoken British singer gets a little psychedelic and freely shouts out -- and even throws a little shade -- at her fellow female pop stars.

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

Katy Perry is no stranger to adopting hysterical personas for her music videos (remember Kathy Beth Terry from 'Last Friday Night'?), but she has gone all out in the vid for her latest single, 'Birthday.' While the lyric video was sugary sweet, this video is anything but, featuring Perry as five different party personalities all pranking a wide range of birthday parties.

Think you know Katy Perry better than Katy Perry herself? Well, a Katy Perry-o-phile named Emily thought she did and competed against the singer on a hilarious faux game show skit on 'Jimmy Kimmel Live!' last night (April 21).

Today (April 19, 2014) is National Record Store Day and each year, musicians release special vinyl, cassette and CD albums to encourage fans to head to their local record store and support the industry. We take a look at some big name pop stars who have something special planned for fans. So grab this list and head on over to your local record store!

Fans, next time you see Katy Perry, you might want to think twice about taking out your cellphone and trying to grab a selfie with the pop superstar.

Move over, Robert Pattinson, Riff Raff and John Mayer, the rumored hookups and official ex of Katy Perry. The singer and supreme catch may be dating DJ Diplo.

Ever since Katy Perry announced she was teaming up with mall retailer Claire's for an accessories line, we've been waiting to get a look at the Perry-branded items, since her personal style is so unique and was bound to assert itself in these pieces. Well, photos of the earrings, necklaces and more have leaked online.

They're both single at the same time, so did something in the hot, Cali desert air at Coachella stir up romance with longtime pals Katy Perry and Robert Pattinson?

Warning: You will want to nom all of the incredible-looking confections in Katy Perry's lyric video for her song 'Birthday.' Just letting you know in advance.
