On Aug. 24, Cyrus appeared in a photo alongside Siwa's family at "America's Got Talent." In the picture, which Siwa's dad shared on his Instagram account, Cyrus is smiling in front of the XOMG Pop sign with Siwa's parents. While it's unclear how long Cyrus and Siwa have been dating, the fact that the TikToker was hanging out with Siwa's family was definitely a hint at their blossoming relationship.
