Cyrus revealed in a comment on a TikTok post on Saturday.
Sharing a video from a tropical getaway, Siwa can be seen in the video telling Cyrus, “This is my sorry for breaking up with you present.”
In the comments section, one fan wrote, “Now I just want to know why,” to which Cyrus responded: “We decided that we are better off as friends! We are both so young and still just trying to figure our stuff out.”
The former couple first sparked romance rumors after they filmed a TikTok video alongside each other on Aug. 5. The duo was seen mouthing the words to a voiceover by Scott Disick and Kourtney Kardashian.
“We’re friends,” lip-synced Siwa. “Purely platonic,” mouthed Cyrus — prompting Siwa to laugh.
Cyrus and Siwa continued to appear in each other’s social media posts in the weeks that followed, while also leaving flirty messages in each other’s comment sections.
On Sept. 13, Cyrus and Siwa made their relationship official with a TikTok video that showed the two kissing in a Chuck E. Cheese photo booth. Two days later, the couple made their red carpet debut.
Then, in October, Siwa revealed that she was officially off the market, posting an Instagram photo dump that included one of a “JoJo Be My GF?” sign made by Cyrus. She then gave proper confirmation in a YouTube vlog.
“We’re girlfriends now. I’m so happy you said yes. I knew you weren’t gonna say no, I was just nervous,” Cyrus said, to which Siwa replied: “I’d be insane if I said no, you’re the best girlfriend in the world.”
