If you have siblings, you know all too well that sibling rivalry is real. But you also know that siblings make the best friends — and a ton of celebrities clearly feel the same way. Some of these stars with built-in BFFs won’t come as any surprise. Like, c’mon, has anyone managed to miss the one million Instagram posts from the Kardashian-Jenners reflecting what a tight-knit crew they are (sans the occasional spat between Kim and Kourtney). Did you realize Jessica Alba’s brother is her bestie, though?

It actually makes a lot of sense that celebrities might lean on their siblings more than most. Fame can be a weird world to navigate. There’s intense scrutiny. Stars undoubtedly feel like they always have to be “on.” Having someone in their corner who understands all the quirky, more personal parts of their personality — the ones they’re able to keep out of the public eye — must be comforting. And for some celebrities, they have the added benefit of having a celebrity who also understands the business.

Maybe Liam and Chris Hemsworth vent to each other during their downtime back home in Australia about having their love lives dissected in headlines. Kate and Oliver Hudson even launched a podcast together. Solange Knowles and Beyoncé won’t let anything come between them.

I literally watched her pour her heart and soul into this film, surviving on little to no sleep. You cannot fathom the work she put into this in front of and behind the camera. Her DNA is sprinkled throughout like magical fairy dust. I honestly don’t know how she does it all. I’m bursting with pride!”

“She is my other half,” Hunter once told Parade of his celeb twin. “Nothing is more important to me than my twin.”

“He’s the most golden-hearted person,” the actress then said of her brother. “I think a lot of people spend their life looking for a partner, someone to be a mirror to reflect upon, to remind them that they’ve lived. You want someone to tell you what he witnessed in your life. My twin brother has always been that for me.”

So our family is like any other family. We have our situations and our s—, but our deepest desire is to connect. And I think we all really have a strong desire to make that happen.”

Nowadays, the two work together on Dancing with the Stars. Derek is a judge while Julianne is a co-host!

“My sister has always been brilliant,” he gushed about his sister to The Hollywood Reporter. “What it did was present something to me that I inevitably would always be chasing.

“Well it’s inevitable to fight, but it’s always to know [that] you’re going to come back from it,” Bella said of The Drew Barrymore Show of her sister. “And that is what’s so important about my sister and I going through life like we’re best friends. And regular sister stuff, like stealing clothes, getting the front seat, what music we were gonna listen to. She was a Swiftie, I loved Lil Wayne, that was really hard for the school drives,” she joked.

Lupita & Peter Nyong’o

Remember the iconic Oscars selfie back in 2014? Well, Lupita Nyong’o’s brother Peter is in the photo alongside some major A-listers as he attended the event as his sister’s plus-one.

The pair have clearly been close ever since.

In 2020, when Peter tied the knot, the Oscar winner celebrated the moment with her followers. “Yup, he is off the market, folks!” Lupita wrote on Instagram, per Entertainment Tonight. “Sharing a moment of joy in my family’s life when my sweet, gentle, loving baby brother @juniornyongo made his declaration of love to his new bride @wanjawohoro this week. Welcome to the family, Wanja!”

Another talented sibling duo in this list is Chris Evans and his Barbie star brother, Scott Evans.

“We were each other’s first friends when we were kids. Up until we were older, too. There was never a time where it didn’t feel like he wasn’t my best friend. And he still is,” Scott told Attitude of their bond. “And we have a really, really, incredibly unique bond that I love.”

“I think the relationship between brothers can be very unique,” he continued. “It feels like a best friend as opposed to feeling that you have to love someone because they’re family.”

“I used to go to him with all my problems,” he said. “And I get calls now from him with his problems. And I love it. I’m like, ‘I’ll give you advice? You’re Captain America!’ “

In July of 2024, for example, Jessica was her sister’s biggest cheerleader when she returned to the stage to sing after her hiatus. “I woke up this mornin’ cryin’ like a fan girl nerd sister watchin’ this from last night!!!” she wrote on Instagram. “You are a fuckin’ rockstar Ash! You looked, sounded, and moved like you never missed a day on stage. It was simply EPIC!”
