Miley's manager shut down the rumors, however, telling Us Weekly the two are not married: "[It was] just some great photos that happen to have been taken in a white dress."
ET has reached out to Miley and Liam's reps for comment.
The couple, who met on the set of 2010's The Last Song rekindled their romance last March after calling off their engagement in 2013. Ever since, the two have not been shy about gushing over each other via social media, and packing on the PDA.
Last October, Miley opened up about wearing her Neil Lane engagement ring from Liam again during a guest appearance on The Ellen DeGeneres Show.
"It's very weird because this is, like, real jewelry and most of my jewelry is made out of gummy bears and cotton candy and they don't look that good together because they kind of mix up," she joked. "So, sometimes I replace it with an actual unicorn or a Looney Tune. And he's like, 'What's going on?' And I'm like, 'Well, this isn't my aesthetic, but I'll wear it 'cause you love me.'"
