Earlier this week, Elon Musk posted to Twitter one of Miley Cyrus' biggest secrets.
Hannah Montana and Miley Cyrus are the same person.
Musk's tweet was a photo of someone with a Guy Fawkes mask captioned with the words:
"Hannah Montana is actually Miley Cyrus."
The hit Disney TV show premiered in 2006, over 15 years ago. The secret has definitely been out for quite some time.
But Cyrus still followed up with a hilarious response on Twitter:
"What the f*ck @elonmusk?!?! I told you that in confidence! You can build a rocket but can't keep a damn secret?!?!"
Some people went along with the joke.
Many—who probably watched the show as kids—found this a lovely break from the stress that can be Twitter.
But a few people do not like the idea of a Musk and Cyrus friendship.
Musk did give a reply to her protests saying he was 'hacked' and that's how her secret was leaked.
This wasn't the first time the two celebrities have been seen going back and fourth on Twitter.
After Elon Musk made his appearance on Saturday Night Live, he responded to a hilarious tweet suggesting a collaboration.
So Cyrus of course had to chime in.
We aren't sure where this Twitter friendship will going next, but it could either end in a musical collaboration...
...or a trip to outer space.
