John Luke Robertson and Mary Kate McEacharn got married about two weeks ago and the happy couple shared a ton of adorable honeymoon photos from their trip to Australia.

The 19-year-old "Duck Dynasty" star proposed to Mary Kate in October, and at the time, he told E! News that he was "so excited to marry his best friend." Now, just a couple of months later, they're married and loving every minute of being newlyweds. While in Bali on their honeymoon, they went snorkeling and rode jet skis. Mary Kate was sure to post all the beautiful photos to her Instagram, while John Luke kept it simple and sweet with just one post.

His one post was of the two "exploring" on the beach with a gorgeous view in the background. "Island exploring with my woman," he captioned the photo.

Mary Kate started sharing photos from the trip last Wednesday, with a selfie of them smiling in snorkel gear. "Honeymoon: part 2, day 1," she wrote. She then went on to post an underwater shot of some fish, a photo of herself reading and relaxing on the beach, one of them in matching bathing suits getting ready to jet ski, and a delicious looking breakfast.

Her most recent post, though, may be the cutest of them all. It's another selfie of the happy couple. This time, they're on a boat surrounded by the most beautiful blue water as she kisses John Luke on the cheek. "These past two weeks were an absolute dream," she wrote. "But happy to be heading back to Louisiana."

They've only been married for about two weeks, but they they're just beaming with excitement over the idea.

"I had an amazing time," John Luke told Us Weekly following the wedding. "It was one of the best days of my life," Mary Kate added. "It was everything I hoped it would be and more."
