Miley Cyrus denied splitting from her fiance Liam Hemsworth this week, before announcing a Twitter hiatus to get away from all those nasty social media rumors. "I didn't call off my wedding. Taking a break from social media. #draining," she told her 11 million Twitter followers earlier Wednesday (March 6, 2013). And then she got photographed without her engagement ring,

Yep, the 20-year-old stepped out in Los Angeles later that night, sans ring. The 3.5-carat diamond Neil Lane rock was given to her by Hunger Games actor Hemsworth last year, though it was nowhere to be seen on Wednesday. The news comes after reports surfaced Miley was unhappy with her boyfriend of three years after he got a little too close to 'Mad Men' actress January Jones following a pre-Oscar party at the Chateau Marmont.

The pair were snapped in the backseat of a waiting car before being chauffeured away from the celebrity hotspot, while Life & Style report things got a little steamy afterwards. The magazine says the pair "went to a private house party, and right in the middle of the party, January was clinging to Liam, saying, 'You're so handsome." The actor was apparently heard saying, "We can't do this here," while a guest said, "they left holding hands and went out in the hallway and were making out. She was wasted. It wasn't good."

Despite Miley ditching the bling, a source close to the pop-star told People magazine, "The wedding is still on..Miley and Liam have had some problems that they are working through."
