But now Ari has been forced to defend herself after a fan claimed she cheated on ex boyfriend Mac Miller when she got together with Pete.
The fan wrote on one of her insta photos saying 'Ari cheated on maccccccc.'
But Ariana was quick to shut down the rumour, hitting back with a savage reply.
"I didn't but go off. can you like...go stan someone else ? ur boring" she wrote.
It isn't the first time Ariana has been forced to defend herself about cheating rumours.
When word of her relationship with Pete first surfaced, people accused her of moving on two quickly, implying there was a cross over between Mac and Pete.
But whatever the situation is, it's none of our business.
Let's just let the girl live!
