miley-defends-f-bombs.jpgMiley Cyrus is currently on vacation in Costa Rica with boyfriend Liam Hemsworth, but unfortunately a run-in with a nasty fan has put a bit of a damper on her trip to paradise.

Before boarding a helicopter, Miley was filmed by several news outlets taking pictures with a group of young ladies. Miley had to cut things short after a few minutes, and she was heard telling one fan, “Babe, babe. I gotta go. I’m sorry. I gotta go, honey.” Someone in the crowd then shouted an obscene insult at the 19-year-old singer, to which she fired back, “What the f***? Are you for real? We're on vacation, I'm not being an a******, we're on vacation."

Hundreds of fans have written messages of support to Miley, and yesterday she tweeted, "Been trying not to tweet & just enjoy the holidays but just to clear something up I would NEVER swear to a fan. When someone yells something SO rude making ME look like an "a**hole" infront of fans who I am more than happy 2 take a picture w/ i cant tolerate that kind of rudeness. Every1 who was there apologized 4 the womans brusque behavior. She obviously wasnt a fan. Hope every1 has a Merry Christmas! LOVE 2 ALL!"
