The 27-year-old actress married Ian Somerhalder in April, and she took to Instagram today to share a video of their big day.
Gushing over Ian, 36, Nikki wrote: “You are my every dream brought to life. We are a cosmic collision. This is a lifetime felt in every moment I’m by your side.
“My love, my human, happy one month.”
The accompanying video clip was a montage from the wedding, showing Ian and Nikki’s first dance, them getting ready to say ‘I do’ and him kissing his new wife.
Earlier this month, Vampire Diaries actor Ian took to Instagram to pay tribute to Nikki following their Costa Rican honeymoon.
He wrote: “Feet back on US soil aka… New York City. Dreaming of the Costa Rica rainforest.
“Thank you to this beautiful country: its land and its people. Thank you to this beautiful woman who makes every day a dream come true. Pura Vida.”
The couple, who married nine months after getting together, have started up a joint production company and own a horse named Eagle.
