The 'Who Owns My Heart' singer took to Twitter today (March 6) to complain about false reports suggesting trouble between herself and her fiancé Hemsworth.
Cyrus tweeted: "I am so sick of La. And sick of the lies that come with it. I didn't call off my wedding. Taking a break from social media. #draining."
Rumors of relationship problems emerged due to allegations in the tabloid press that Hemsworth kissed Mad Men actress January Jones during a pre-Oscars party.
A friend of Hemsworth and Cyrus has since refuted those allegations by insisting that the couple are happier than ever.
Cyrus announced her engagement to Hemsworth in June 2012 after dating her Last Song co-star for several years.
