Miley Cyrus Curses At Rude Fans In Costa Rica: UPDATE (VIDEO)

A recent trip to Costa Rica hit a sour note when Miley Cyrus' fans started feeling a little too entitled.

While trying to board a helicopter with boyfriend, Liam Hemsworth, the singer stopped to pose for photos before telling Hemsworth they had to get going.

As the 19-year-old turned to walk away one fan yelled out, "Asshole!"

If you've been paying any attention to Miley lately, you know she stands up for herself. Clearly annoyed, Miley turned around and replied, "What the f**k? Are you for real?"

The incident was caught on camera and later aired on a local news station. It looks like the singer ended up posing for a few more photos before she and Liam took off in their helicopter but seemed less than impressed with her demanding fans.

UPDATE: Miley has since responded to the incident on Twitter. She wrote:
