Cyrus, 23, dressed casually in a white T-shirt by which she paired with denim shorts. Hemsworth, 26, kept a low-profile wearing a white shirt, board shorts, navy cap and black sunglasses, reported People magazine.
Although the pair did not show any signs of PDA, the singer was wearing the 3.5 carat engagement ring she had received before they split in 2013.
Later that same day, Cyrus was pictured shopping at a local boutique with Hemsworth's sister-in-law Elsa Pataky.
