The teen star officially came out of the closet two years ago today.
The Nickelodeon alum and her ex broke up after three months together.
Siwa gave Cyrus a present to apologize for their split while away on vacation.
She also recreated a scene from Harry Potter and the Sorcerer's Stone on TikTok.
In July, Siwa called the Fuller House actress the rudest celebrity she'd ever met.
"Little me, she didn't know she was gay," Siwa shared on TikTok.
