But Hemsworth, while accepting the Film Breakthrough Award for his Hunger Games performance at the Australians in Film Awards last night, was recalling meeting Cyrus on the set of The Last Song when he added, "And now we're married."
Hemsworth did say that, but he was just getting ahead of himself.
"I was fortunate enough to get called back in to read with my now fiancée, who I recently got engaged to...and we read together and fell in love and now we're married," the 22-year-old actor said.
"Well, not married yet," he quickly added. And Cyrus, bless her little fearless heart, yelled, "We will be!" from her seat.
"We will be," agreed Hemsworth.
We've certainly been privy to worse gaffes. At least this one was adorable!
Last night marked the happy couple's first red carpet together since announcing their engagement. They've had to spend a fair amount of time apart, with Hemsworth in New Orleans shooting the cop drama Empire State and Cyrus going to Miami to work on her next album.
