The talented duo attended Luke Hemsworth’s wife Samantha’s gold-themed birthday party this weekend and went all out for the theme, from gold shorts to glittery eye shadow and even a gold medal. The pair posed for photos with an epic gold horse alongside Liam’s big bro Luke and Cyrus’s tour partner, Wayne Coyne of the Flaming Lips. The former Hannah Montana star looked sporty in a gold jersey with what looked like an Olympic medal around her neck and accessorized with matching eye shadow and sunglasses. Cyrus's hunky beau showed off his muscles in a “Gold’s Gym” tank top and dazzling metallic shorts. The Hunger Games star, though, was shown up by Luke (big brother to both Liam and Chris Hemsworth), who went all out in a gold button-down and shiny matching pants. “I even had gold mankini on underneath,” he wrote in the caption of a post starring Liam and Coyne: It looks like his wife Samantha enjoyed her big day. She took to Instagram to share a hilarious picture with her hubby. “So we had a birthday theme #goforgold #spelldesigns #winning,” she captioned the photo.
