We think Katy Perry needs to clear her dance card when she sees this adorable video in which openly gay Army Ranger Ken Yasger invites her to his upcoming Army Ranger Ball.

Katy Perry shines bright on her latest Billboard cover in advance of the release of 'Prism.' But she had to wade through the darkness --a divorce, shade from Barbara Walters and suicidal thoughts-- to get here.

The iHeartRadio Music Festival commandeered Sin City this weekend. In case you missed it and couldn't make it, we've recapped the event in the form of live photos of Miley, Katy, JT and more. Go ahead, check the photo recap out. These pics will make you feel like you were there.

Katy Perry and her baby blues cover ELLE Canada for October. Instead of a body shot of the singer wearing a gorgeous, high fashion couture ensemble, the cover image zeroes in on Perry's haunting, crystal blue eyes and her features.

Courtney Love has had her share of controversy, so it's to no one's surprise that the former Hole frontwoman had something to say about the 2013 MTV Video Music Awards -- specifically about two of the night's biggest performances from Katy Perry, who boxed and did the mildest of choreography, and Miley Cyrus, who twerked on Robin Thicke's crotch.

Katy Perry and John Mayer are getting super serious, but as anyone who's followed their tumultuous relationship knows, they've had quite a few ups and downs -- including quite a few splits -- in between. Thankfully, though, those are behind them ... and they even inspired Perry's smash hit, 'Roar.'

Miley Cyrus and Katy Perry will help make Saturday nights even more exciting very soon. Both artists are among those set to appear on 'Saturday Night Live' this season, NBC confirmed today (Sept. 9).

John Mayer and Katy Perry are back together in a big way. It's not only good for their careers (they keep gushing about one another to the press to promote their new albums 'Paradise Valley' and 'Prism'), but also for their hearts. Turns out, Mayer is even considering taking the next step with Perry. What's that step?

Katy Perry pulled a Rocky Balboa when she closed out the 2013 MTV VMAs tonight (Aug. 25)! The songstress donned fire-emblazoned boxing trunks and performed her new smash 'ROAR' for the first time in a makeshift boxing ring under the Brooklyn Bridge. She was a champion and all of Brooklyn heard her roar.

Katy Perry closed out the 2013 MTV Video Music Awards with her new hit single, 'Roar,' from under the Brooklyn Bridge ... and she was a true knockout.

The 2013 MTV Video Music Awards will go down tonight (Aug. 25) at the Barclays Center in Brooklyn, N.Y. -- but not all the performers will take the stage inside Jay-Z's home turf. Show closer Katy Perry will perform outside the venue ... and under a bridge! Is this a metaphor for literal trolls to the Internet trolls who keep pitting her against show opener Lady Gaga?

Katy Perry sticks to her guns! The 'Roar' singer took another page from Lady Gaga's book, going head to head with Australian politician Tony Abbott, refusing to vote for him because of his stance against gay marriage.
