Finally fed up with the relationship rumors, Miley Cyrus refuted claims that she and fiancée Liam Hemsworth have broken up.

On Wednesday (March 6), the "Hannah Montana" star 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."

That break was a short one as an hour later she tweeted, "my new music is gonna shut everyone up," followed by, "not discussing anything but my music from now on."

As for those rumors, a source tells PEOPLE, "The wedding is still on. Miley and Liam have had some problems that they are working through. Miley doesn't think it's a big deal. She loves Liam and can't wait to marry him."
