Videos posted by Conrad Carr, a friend of the couple, show Hemsworth in a tux, doing a shotski with his brothers, fellow actors Chris and Luke. Another clip from Carr’s public Instagram story shows Hemsworth and Cyrus ― in white ― holding a knife about to cut what looks like a wedding cake. The singer’s mom, Tish Cyrus, is pictured in the background. Conrad Carr/Instagram Conrad Carr/Instagram HuffPost reached out to reps for both Cyrus and Hemsworth, but there was no immediate response.
