Cyrus retaliated, saying: "What the f**k? Are you for real?". A clip of the incident later surfaced online.
The singer has now defended her actions via Twitter, writing: "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' in front of fans who I am more than happy 2 take a picture w/ [with] I can't tolerate that kind of rudeness. (sic)
"Every1 who was there apologised 4 the woman's brusque behaviour. She obviously wasn't a fan. Hope every1 has a Merry Christmas!" – DS
