It's finally happened. Taylor Swift and Tom Hiddleston are Instagram official.

If a tree falls in a forest, and no-one is around to hear it, does it make a sound?

Likewise, if two celebrities start dating, and they don’t take to social media to share the news, did it really happen?

The world has been scratching its head in confusion at the sensation that is Hiddleswift, asking over and over if theirs is a real love between Taylor Swift and Tom Hiddleston, or if it’s all part of a magical musical conspiracy.

Well, you guys, ask no more.

It’s official. It’s real. It’s love. (According to Instagram.)

One of Taylor Swift’s besties, Britany LaManna, has blown the lid on Hiddleswift, sharing a sweet snap of the pair canoodling on the porch of the singer’s Rhode Island mansion.

Alongside Blake Lively and Ryan Reynolds, of course.

Maybe in celeb land you need another A-list couple to stamp their approval on your love… kinda like how you have witnesses sign the documents at your wedding. Maybe.

Tom and Taylor are SO IN LOVE they can't even look at the camera, and they're even wearing matching shoes.

Ring the wedding bells. Sound the baby bump alarms.

Thankfully, Tom changed out of that bizarre 'I Heart T.S.' tank top for the snap, switching to a plaid shirt, which is oh-so-American and very Fourth of July.

It was a busy holiday weekend for the Wildest Dreams singer, who spent the Independence Day holiday surrounded by her nearest and dearest celebrity friends, including Ruby Rose, Gigi Hadid, Cara Delevingne and Karlie Kloss.

Tough life, huh?
