The 24-year-old American singer and 26-year-old Australian actor shared a sweet kiss in a new photo Monday after spending Christmas weekend with Hemsworth's family.
"Whatever," "The Hunger Games" star captioned a picture of Cyrus smooching his cheek while mom Leonie Hemsworth hugs him from the side. Cyrus also posted the snapshot on her account, writing, "REGRAM" with several heart emojis.
Cyrus and Hemsworth had celebrated an early Christmas with the singer's family last week.
The pair spent Christmas morning with Hemsworth's dog Dora and later met up with the actor's family, including his brothers Luke and Chris Hemsworth.
"Thinking about how lucky we are to spend Doras first Xmas together as a fam! Our big and beautiful rescue [dog]!" Cyrus captioned a photo of herself with Hemsworth and his pooch.
Cyrus and Hemsworth reconciled in January after ending their engagement in 2013.
Sources told E! News in October that the couple are happily living together and "going stronger than ever."
"Miley really loves nesting with Liam. She's loving just being at home with him," an insider said. "She cooks a lot. She loves trying out new recipes all the time."
Cyrus last released the album Miley Cyrus & Her Dead Petz in 2015, and will serve as a coach on "The Voice" Season 13.
