It’s National Best Friends Day! And not only that, it’s also National Soulmate Day. People usually talk about having one soulmate in life, if you even believe in soulmates at all. This soulmate is usually someone you have a romantic relationship with, someone you might end up marrying or staying with for a long time.

I personally think each person has more than one soulmate, and these aren’t necessarily romantic partners. They definitely can be, but don’t you have that one friend (or several) that you know you will always love no matter what? Your soulmates could also be people in your family, those that you feel connected to in a way that is unlike your relationship with others.

I believe our soulmates are destined to be in our lives at one point or another. And for some celebrities,  they just so happen to meet their friend soulmates or besties while working. Like Zendaya and Hunter Schafer on Euphoria, or Zendaya and Timothee Chalamet shooting Dune, or Zendaya and Tom Holland getting together after working together on the set of SpiderMan… I think it’s pretty obvious that Zendaya might be the easiest person to be besties with. But we already knew that.

It totally makes sense that you’d get close to other actors while on set, since you’re spending so much time with them. Inspired by a list by US Magazine, these are some of the celebs who found best friends within their costars.
