We can officially confirm the latter: The new couple has seemingly adopted a horse together.
Somerhalder shared a picture of the stunning stallion, named Eagle, on Instagram Tuesday.
"Proud new dad ... What amazing creatures they are. Wow," he wrote, adding a shout-out to his gal pal. "Thank you @iamnikkireed for snapping this special moment, with our big baby boy."
You heard that correctly, right? Our baby boy.
Clearly, these two are bonding over their fondness of all things furry. The Twilight actress, 26, who has two German shepherds – one of which she adopted with her 'ex-husband Paul McDonald – frequently shares photos of herself riding horses on her own Instagram feed. She's also playing an equestrian in the film The Sunday Horse, which is due out next year.
And the Vampire Diaries star, 35, who has a dog named Nietzsche, has also made no secret of the fact that he's a fan of the feline kind. In 2010, he told PEOPLE, "I have three cats in my loft in Atlanta. I literally wake up, and there's just fur everywhere. It's so awesome."
