Miley Cyrus was clearly feeling rather spirited when she cupped her assets playfully while wearing a very risqué cut-out dress.

Both Miley and her husband Liam Hemsworth, also appeared to have a playful lovers’ tiff as they arrived at the Avengers: Endgame premiere in Los Angeles on Monday.

Liam, 29, who married Miley last year, reached over to touch his wife’s stomach, before she pushed his hand away and scowled at him in front of the cameras.
