Cyrus recently shared an Instagram Stories video of Hemsworth driving while she sits in the passenger seat, happily dancing to a rap song. While at first 28-year-old Hemsworth dances along as well, he later ruins her video, exclaiming "oh s**t!" and pretending to lose control of the vehicle.
"I f**king hate when he does this s**t," Cyrus, 25, wrote about the video on Instagram.
Of course, this isn't the first time Hemsworth has ruined Cyrus' selfie video. In August 2016, she shared a cute video of the two singing along to Justin Bieber's "Love Yourself" before Hemsworth pulls the same prank.
"They have been in love for almost nine years, but the timing has never been right until now," the source said. "Their massive careers, their ages and their families' input has kept them from getting married."
Cyrus and Hemsworth were first engaged in 2012, but announced they had split the following year. The two later reconciled and, according to the source, have learned from what went wrong the first time around.
"They felt such pressure to make it the most spectacular wedding in the world," the source explained. "But that was the downfall of their relationship and led to their breakup. This has been such a long, drawn-out process. They joke about the idea that when they finally get married, people won't believe it's real!"
