Liam Payne and his girlfriend Danielle own a puppy. So they might as well be married.

We can tell when a relationship's gotten for-real, Facebook-status-change serious from two things: a requisite lovey-dovey tweet, Instagram, Snap-chat, Vine etc. (we're looking at you, KIMYE!) and WHEN A COUPLE ADOPTS A PET! Which brings us to our next announcement: One Direction's Liam Payne and his girlfriend, Danielle Peazer, have just co-adopted a pet dog named Loki! And we say "co" because they both own it, which basically means they're going to get married they've taken things to a WHOLE new level.

Read more about Liam and Danielle's new dog after the jump.

Like all good pop stars' girlfriends should, Danielle introduced her new doggie via social media, tweeting, "The new love of mine and @Real_Liam_Payne's life..... Loki xxx." Further cementing their coupledom, Liam wrote a follow-up tweet with yet another pic of his adorable new pup: "Everybody meet mine and @daniellepeazer new dog Loki ." Yeah, so by our calculations, that's two dog-centric tweets and two photos of said dog, which would probably put Liam and Danielle at the alter in about, oh, a year/year-and-a-half at most! It's just numbers game, guys.
