Singers Miley Cyrus and Katy Perry have been friends for many years. They’ve been photographed at many events together, from the Grammy Awards to the Kids’

Choice Awards. In fact, their first time meeting was at an awards show. According to Cyrus, the two have known each other “for a really long time.”

“We were actually just realizing the other day that next year, we’ll have been friends for 10 years,” she said in a May 2017 WKTU interview, as reported by E! News.

“I think that’s my friend that I’ve known the longest.” A few months later, Cyrus shared a photo of herself, her sister Noah Cyrus, and Perry, from the latter’s Witness tour, on Twitter, writing, “Sisters. All 3 of us.”

How did they become friends? Cyrus went on to explain that, after hearing Perry wrote her breakout hit, “I Kissed a Girl” about her, she “screamed and started freaking out.”

The two then attended the VMAs together, along with Cyrus’ mom, Tish Cyrus, beginning their friendship. (Perry has since changed her tune, saying that she wrote the song about Scarlett Johansson.)

But there have been some speedbumps in their friendship. After Cyrus kissed her for real at a February 2014 concert during her Bangerz tour, a sort-of feud began.

Perry’s comments on an Australian morning show the next month indicated that she didn’t like how Cyrus “tried to move her head and go deeper” with the kiss, according to The Hollywood Reporter‘s transcription of the interview.
