In a sweet Instagram message, the 38-year-old gushed about his partner of three years, who is currently pregnant with the couple's first child.
"Happy Birthday to the most amazing human I know... Today, we celebrate you," Ian captioned a gallery of the pair's cutest selfies. "For an innumerable amount of reasons, I couldn't even begin to describe, as all of those who know you and those who even don't know you, would agree. It's your day. The love and light you radiate to the world shines like a beacon for all to see."
While it starts simple enough, it wasn't long before we were reaching for our tissues.
"Its that love and light that guides me to the safe shores of home from the turbulent and sometimes treacherous waters of life. Thank you for your tireless pursuit of spreading good, being an instrument of change and seamlessly weaving the complex threads of our lives together into the warmest, softest and most magical blanket," he continued. "Every day I get to watch you being you I'm constantly reminded of your beauty and prowess and how lucky I am to share this life with you."
We're not crying, you're crying.
Unsurprisingly, Ian's tribute to Nikki, 28, has amassed over 1 million likes and counting since it was posted.

While Ian's poetic words stirred our hearts, Nikki has also gushed about The Vampire Diaries star in the past.
"My guy, my man, my honey, my partner in this life, my better half in every way," she wrote on their wedding anniversary. "At exactly this time two years ago today we walked hand in hand into the next chapter, our chapter, together. Every day gets better, every moment calling for even more. Navigating the waters of life with you is the greatest and most rewarding adventure I've ever known."
She continued, "We climb, we grow, and we laugh at all of it. Thank you for being exactly who you are, and for loving all of me. Thank you for your willingness to go even deeper. Until you, I had no idea what could be."
This vampire love is real.
