Ian shared a new photo with fans as he and Nikki returned to New York following their romantic honeymoon.
Captioning the photo, he said: "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, the newlyweds look blissfully happy as actress and singer-songwriter Nikki rests her chin against Ian's shoulder, while the shirtless actor smiles and looks into the distance.
Late last month, Ian and Twilight star Nikki secretly tied the knot just two months after announcing their engagement.
And this week, Ian's ex-girlfriend and co-star Nina Dobrev spoke about his wedding to Nikki, saying it was "beautiful".
She told E! News: "When I heard about the wedding, I thought it was beautiful. They look happy and I am happy, so I don't see why there should be a problem with that."
