The 36-year-old Vampire Diaries star and the 26-year-old Twilight star are engaged.
Since hooking up, the love-birds have adopted several animals together. In August, they proved they were getting serious by adopting a horse named Eagle. "Proud new dad... What amazing creatures they are. Wow. His name is Eagle. Thank you @iamnikkireed for snapping this special moment, with our big baby boy," Somerhalder wrote on Instagram at the time with a photo of their new family member.
Two months later, the duo adopted a precious kitten.
