The "Wrecking Ball" hitmaker took to Twitter on Tuesday, June 11, to celebrate the relationship milestone by sharing throwback photos of the couple from the set of "The Last Song", the 2010 Nicholas Sparks movie on which the stars met and fell in love.
"Started diggin (sic) you in 2009 @LiamHemsworth," she wrote. "S**t got deep... Happy anniversary."
Miley also took the opportunity to mock tabloid coverage of their romance, which was frequently reported to be on the rocks.
Alongside a screenshot of a Gossip Cop article ranking the "Miley Cyrus, Liam Hemsworth Split Rumors" as fact or fiction, she added, "Happy 10 year anniversary my love. Good to see everyone is as dumb as they were in 2009!"
"Some things never change .... & I hope the way you feel about me is one of them. (Yours) truly."
Miley and Liam initially became engaged in 2012, but called off their wedding plans and parted ways in 2013.
They rekindled their romance in late 2015 and tied the knot in a low-key ceremony at their home in Tennessee in December (18).
