Ian Somerhalder Thanks His "Beautiful" Wife, Nikki Reed, in Shirtless Instagram Photo

Ian Somerhalder and Nikki Reed's tropical honeymoon may be over, but they're definitely still in the honeymoon phase! Ian posted a sweet photo from their trip on his Instagram account on Wednesday, with the caption, "Feet back on US soil aka . . . New York City. Dreaming of the Costa Rica rainforest. Thank you to this beautiful country: it's land and its people. Thank you to this beautiful woman who makes every day a dream come true. Pura Vida." In the photo, a bikini-clad Nikki nuzzles into her shirtless husband's neck while smiling at the camera.

Ian and Nikki, who got engaged in January after six months of dating, tied the knot on April 26 in a gorgeous ceremony in Malibu, CA. The couple then took their newlywed PDA around the globe. They were first spotted getting cozy on a beach in Tulum, Mexico, before jetting off to Rio de Janeiro, Brazil, for a cute double date with Ian's Vampire Diaries costar Paul Wesley and his girlfriend, The Originals star Phoebe Tonkin. The last leg of their romantic getaway seemed to be Costa Rica, where Ian snapped the cute pic. Check out their newlywed glow above, then look back at some of their sweetest PDA moments.
