Few friendships seem as pure as the one between two of the most popular names in pop music — Taylor Swift and Selena Gomez. Their commitment to their relationship is quite a rarity in Hollywood.

Sure, there have been other celebrity best friendships over the years that have given us major friend envy, but what makes the bond between Swift and Gomez so awesome is that it reflects a larger truth — it's all about the quality, not the quantity of friends.

Girl squads are great in theory. The more, the merrier. Girl power for life! But in the end, it's really your bestie who's there for you through it all.

You don't need a huge squad to be happy; you just need a Selena to your Taylor. Someone to help complete your Taylena.

They each have their ups and downs with relationships. They each have their own wildly dedicated fans. They each have their own major record deals. But at the end of the day, there's nothing better than having a bestie who just gets ya.

As we age, our friend groups tend to shrink. We're busy balancing work life, family life, and social life — and often tripping up along the way. We're moving jobs, moving cities, and even shifting our friend groups. It's times like those when you don't need to be in massive group texts trying to coordinate where to get brunch, but rather getting a quiet cup of coffee with a best friend and just taking a breather.

If you're in need of that one-on-one BFF time, then you're in luck, because June 8 is National Best Friends Day. Below are all the times Swift and Gomez proved that they were the ultimate best-friend duo.

Maybe it'll give you a little inspiration for how to celebrate your own best friend.
