If that unfollow on Twitter wasn't proof enough, representatives for both Miley Cyrus and Liam Hemsworth have confirmed the couple's almost four-year relationship is over.

The pair began dating in 2009 after starring in the movie "The Last Song" together. Hemsworth proposed to Cyrus on May 31, 2012, but rumors have been swirling for a while that the engagement was off. The latest batch of stories seemingly confirming the couple's split involve Hemsworth being romantically linked to January Jones. Cyrus and Hemsworth haven't been seen together since walking the "Paranoia" red carpet in August.

Sites like People and E! Online confirm that Cyrus and Hemsworth are done for good and that the wedding is off. Cyrus is in Europe promoting her forthcoming album "Bangerz," while Hemsworth was seen solo in Las Vegas over the weekend for the Floyd Mayweather fight.
