And no, we're not talking about Miley Cyrus!
The singer is currently on vacation in Costa Rica with boyfriend Liam Hemsworth and his family, and was spotted posing with fans and signing autographs, but as you can see in the video (above) one gets upset when she patiently explains that she has to leave and calls her an asshole, and she is pretty perturbed!
Not that we blame her! She was doing the best she could!
And like she says - this is her vacation, too! Let the girl relax!
