The star posted a charged tweet Wednesday that both confirmed she was still heading down the aisle while venting her frustration at the rumor mill following reports that she'd called off her wedding after her beau was supposedly spotted getting cozy with Mad Men star January Jones.
"I am so sick of La. And sick of the lies that come with it. I didn't call off my wedding," she wrote, adding, "Taking a break from social media. #draining."
Rumors began churning last week that the two, who had just returned from a romantic trip to Costa Rica, were supposedly on the rocks after Hemsworth was spotted at a pre-Oscar bash in Los Angeles with Jones.
Cyrus, meanwhile, was seen attending Elton John's annual AIDS-foundation fundraiser with her mom, Tish.
A source had slammed speculation of a breakup, telling E! News, "They are totally together."
Now, with Miley's vehement denial, everyone's getting it straight from the star.
