The Vampire Diaries actor and his Twilight actress fiancée are reported to have tied the knot on Sunday after photographs of their wedding ceremony emerged on Twitter.
Nikki, who was previously married to singer-songwriter Paul McDonald – can be seen in a stunning long-sleeved lace gown while Ian donned a white suit and shirt.
The former Lost actor – who previously dated his co-star Nina Dobrev – appeared to confirm the news by taking to his Twitter account to gush about the big day, which is thought to have taken place in his hometown in Louisiana.
He wrote: ”most beautiful morning ever…” Ian also revealed that he and Nikki – who got engaged in January after six months of dating – had been working out in preparation for the special occasion after posting a picture of them both lifting weights on Instagram last week.
Meanwhile, Ian’s Vampire Diaries co-star Kat Graham recently confessed that she believes the couple are true ”soul mates.”
She said previously: ”I haven’t met two people that were more of soul mates than those guys. They are so absolutely amazing. Everyone loves them, and I really can’t imagine him with anyone else.”
