Actor Zac Efron and model girlfriend Sami Miro recently enjoyed a day at the beach together. Both looking tanned and fit as they posed for a couple of photos while showing their “swag.”

The hot Hollywood actor took to Instagram on Tuesday, sharing a cute picture of himself with Miro on the sand, reported E! News. The picture shows Efron crouching down, with his left hand making the “Hang 10” sign, with Miro behind him. The actor was also holding a selfie stick, and captioned the photo, "Unlock the swag."

The two looked relaxed and ready for the summer, with Miro gorgeous in a yellow bikini top partnered with tiny shorts, an unbuttoned shirt and sunglasses. Efron, meanwhile, was in shorts, a T-shirt, sunglasses and a baseball hat.

The former Disney star has been busy filming in Hawaii for his movie “Mike and Dave Need Wedding Dates.” Efron and co-star Adam DeVine also went on an ocean adventure, swimming with tiger sharks and even capturing their underwater experience on video. The “High School Musical” star also shared the shark adventure on Facebook, with one scene showing him grabbing a fin of a tiger shark. This elicited mixed responses from shark experts.

Shark photographer Jeff Kurr found Efron’s dive reckless, since grabbing a fin is an “aggressive invite to a deadly attack,” reported TMZ. On the other hand, naturalist Juan Oliphant, who set up the dive for the two actors, told TMZ that the point of the video was to “show the beauty of sharks so people will think twice before poaching them for fin soup.” Oliphant also mentioned that Efron and DeVine were extremely respectful and the shark was “mellow and uninterested in people.”

Meanwhile, Miro recently admitted to having stolen several food items from Efron. In June, Miro told Man Repeller about what she keeps in her fridge, reported Cosmopolitan, and the model confessed to having taken chia seeds from Efron, in order to make kombucha -- a healthy concoction that the couple drinks together. Miro also took some turkey, saying, "The turkey I stole from Zac's house. It is an easy snack to have."
