Fans knew something was up when the rapper took to Instagram on Monday claiming he's been "used." In a since-deleted Instagram post, he added, "I feel like I'm probably being cheated on."
Noah then posted "concerned and confused" on her Instagram followed by a series of her own allegations that Lil Xan cheated on her.
Claiming she saw a picture of a girl on his story at 2am, Cyrus says she noticed a hickey when she FaceTimed him later. "He told me it was just a bruise and I decided to give him the benefit of the doubt."
"Cheaters like to accuse their partners of cheating to make themselves feel less guilt," Noah added.
According to Noah, Lil Xan "spiraled" when she sent him a meme of Charlie Puth. He denies this is the reason for the breakup.
Ready for the kicker? Lil Xan ended his Instagram rant posting a video with another chick.
If you'll recall, the duo were just happy in love during Billy Ray Cyrus' birthday party last week. The rapper even gifted Papa Cyrus a bong.
The big question is ... does Billy Ray have to return the bong?
