Ariana Grande‘s emotional Manchester One Love Benefit concert was viewed worldwide, acting for many as a source of comfort and respite from the terrible violence in Manchester.

In a new video released from the event, we can see Katy Perry‘s experience backstage, including her interactions with fellow performers Justin Bieber, Niall Horan, Miley Cyrus, and, most notably, Ariana.

Katy rehearses her acoustic rendition of “Part of Me,” in the video. She also jokes around with Miley, gives Justin a warm hug, and takes a selfie with Niall, as one does.

“It’s awesome that you’re here,” Justin tells her, smiling big.

The best part of the video, though, is the end. After Katy‘s set, Ariana gives her a long, heartfelt hug that seems to last forever, and that alone is reason enough to watch.

Katy Perry has been breaking records left and right lately! The 32-year-old singer recently became the first person to reach 100 million followers on Twitter, and now she is the first — ever — to have three songs reach diamond status.

You can probably guess which three songs achieved diamond! “Firework,” “Roar,” and “Dark Horse,” smashed records, selling 10,000,000 units each. Casual.

The Recording Industry Association of America broke the news to her, and Katy reacted with her usual chill demeanor.

That is to say, like any normal person, of course she freaked out.

Ed Sheeran and Taylor Swift are super close friends, and they always believe in one another and support one another, helping each other overcome self-doubts.

But, as Ed said at the 2017 Songwriters Hall of Fame, they don’t always need to defend one another.

“I don’t think she needs [to be defended] at all,” the 26-year-old “Shape of You” singer told People. (Since Katy Perry has apologized to T-Swift and dropped the matter, we’re thinking he’s absolutely right!)

He also revealed that he himself has written feud songs before, but that: “no one cares about them!”

Feud songs can be powerful; expressing one’s anger through music can lead to some magical things. That said, when celebrities themselves have dropped their “feud” (as Katy has finally done) it is definitely time for us to follow suit!

Katy Perry released her first album, Witness, just last week (listen here) — but now she is breaking an entirely different sort of record.

Twitter announced today (June 16) that Katy is officially the first person to reach 100 million followers on the platform — ever!

She has been on Twitter for eight years now, with over 8,500 tweets. Her most-tweeted about day was on the 2015 Superbowl (LEFT SHARK), and five of her six most retweeted tweets are about other musicians, Twitter reports.

Congratulations, Katy! This is huge.

Katy Perry seems like she really wants to put her beef with Taylor Swift behind her.

The singer changed one of the lyrics in her song “Swish Swish” during her “Witness World Wide” exclusive YouTube live stream concert today in Los Angeles. (via ET)

The event comes just days after Katy apologized to Taylor for any past drama and said that she totally forgives her as well.

Many have speculated that “Swish Swish” was written about Taylor as a response to Taylor‘s “Bad Blood” (though Katy claims it’s just about bullies in general).

Instead of singing “Don’t you come for me,” in the first verse, Katy changed it to a more positive “God bless you on your journey, oh baby girl.”

WHAT DO YOU THINK of Katy changing the lyrics?

Katy Perry is apparently over her long-standing beef with Taylor Swift.

The “Bon Appetit” singer shared her thoughts about the situation during her live stream, apologizing to Taylor and stating that she totally forgives the “Blank Space” songstress.

“I am ready to let it go,” Katy told Thrive Global founder Arianna Huffington. “I forgive her and I’m sorry for anything I ever did, and I hope the same from her. I love her, and I want the best for her. And I think she’s a fantastic songwriter, and I think that, you know, if we, both her and I, can be representatives of strong women that come together despite their differences, I think the whole world is going to go like, ‘Yeah, well we can do this.’ I don’t know.”

For the past few weeks, Katy has been opening about her feud with Taylor and went as far as saying Taylor tried to “assassinate” her character.

“There’s a lot of other things out there in the world that people need to be focused on, and I truly, like, God bless her on her journey,” Katy said. “God bless her. Honestly.”

Today is a huge day for summer music: Miley Cyrus released her new single, “Inspired,” (listen here), Taylor Swift released her five albums on Spotify, and we can finally listen to Katy Perry‘s much-anticipated “Witness” album (listen here) — on repeat.

Chloë Grace Moretz is a huge fan of the latter. The 20-year-old Red Shoes and the Seven Dwarfs actress took to Twitter today to show her love for the new album — twice.

“Oh my yes this album,” she tweeted, accompanied by a screenshot of her listening to the title track, late last night.

“Yes yes yes,” she tweeted again an hour later, still listening to the album.

We’re glad we’re not the only ones listening to this album’s 15 new songs on repeat today!
