A source told E! News, "It's been rocky, but they are hanging in there."
In fact, Hemsworth is still living at Cyrus' Los Angeles pad and the two were there together last night.
The quality time came just ahead of Miley hitting the promotional trail, as the "Can't Be Tamed" singer is gearing up to release her next single, "We Can't Stop," with the debut happening June 3 on Ryan Seacrest's morning radio show.
"#4dayswecantstop," she tweeted this afternoon.
Meanwhile, Cyrus has been keeping plenty busy, having shot the music video for "Fall Down" with Will.i.am yesterday. She'll be shooting "We Can't Stop" throughout the week in Los Angeles. Liam, for his part, was spotted stepping out solo today for a trip to the gym.
Are you happy to see these two still together? Weigh in below.
