We all saw this coming.

Reps for both Miley Cyrus and Liam Hemsworth have confirmed to People magazine that the pair have called off their engagement .

This past weekend Cyrus unfollowed Hemsworth on Twitter , adding fuel to long-held rumors that the relationship had ended months ago.

Cyrus, 20, and Hemsworth, 23, began dating in 2009 after starring together in "The Last Song," and became engaged on May 31, 2012.

Sources told E! News the split was "Miley's decision, after coming to grips with Liam being what she believed was less than faithful to her."

Back in February, Star magazine first reported that Hemsworth got "hot and heavy" with "Mad Men" star January Jones at a pre-Oscars party at the Chateau Marmont hotel. Those cheating rumors flared up again last week, when Us Weekly reported that Hemsworth has been sexting the 35-year-old actress. A rep for Hemsworth denied the magazine's claim, telling E! News, it was nothing but "tabloid fiction."

Cyrus and Hemsworth's relationship is thought to have been over for a while, as the last time they were spotted together was on Aug. 8 for the red carpet premiere of Hemsworth's film, "Paranoia," in Los Angeles.
