Teen superstar Miley Cyrus has been caught on camera swearing at a rude fan while on a recent vacation in Costa Rica.
The singer/actress was making her way to board a helicopter with her Aussie boyfriend Liam Hemsworth when the couple was stopped by a group of devotees eager for autographs and photos.
Cyrus graciously posed with the youngsters, but, as the pair tried to excuse themselves to board the aircraft, one angry fan cried out, "A**hole!"
In video footage of the incident, which has since surfaced online, a stunned Cyrus can be seen whipping around and shouting back, "What the f**k? Are you for real?", before greeting other waiting fans as she walked over to the chopper.
