These 13 Reasons Why co-stars are besties, and it's the cutest thing ever

If you've seen 13 Reasons Why you know co-stars Miles Heizer and Brandon Flynn's on-screen characters Alex Standall and Justin Foley share something in common: a mutual dislike of each other.

Off screen? That's a different story.

Almost two weeks since the show dropped on Netflix, fans can't stop obsessing over the real-life bond between the on-screen rivals.

The pair have shared their friendship with the world by posting adorable snaps to Instagram since filming began in June last year -- and we can't get enough.

The cast all love to hang out together but these two are killing us with their cuteness.

Here are some of the sweet pics 22-year-old Miles and 23-year-old Brandon have shared.

Some fans of the show have speculated that they're actually dating in real life.

However, a rep for Miles told Page Six that the actors are just friends, saying, "This is a false report. Miles and Brandon are friends from the show but are not dating."

Whatever they're relationship is, we're 100 per cent here for it.

And they're not the only cast members with special bonds! Executive producer Selena Gomez joined actors Alisha Boe (Jessica) and Tommy Dorfman (Ryan) in getting matching semi-colon tattoos over the weekend.

Selena shared an Instagram story of the ink session, writing:  "Wish the rest of the crew was with us today."

The semi-colon tattoos are a symbol that many relate to the struggle of depression, self-injury and suicide and the will to continue on. Project Semicolon began in 2013 as one woman's way to honor the father she lost to suicide.
