In Freakier Friday (out today), they play soon-to-be stepsisters caught between family drama and a body-swap disaster. But IRL, they’re completely in sync—and took our BFF pop quiz to prove it.

Julia Butters, 16 years old

Describe your character, Harper, in five words or less.
Loyal, persistent, layered, strong and surfer.

What’s the number one way you and Harper are similar?
We both appreciate where we come from. Harper values her home and her family, and I’m proud of mine, too. And we’re both from Los Angeles!

And the number one way you’re different?
Harper’s so carefree. She inspires me to care less about what other people think. That’s something I’ve struggled with in the past.

Can you tease anything about the relationship between stepsisters Lily and Harper?
They go to the same school but have very different friend groups. And that results in…let’s just say…some bad chemistry.

How does that dynamic compare to real life?
So different! We’re constantly lifting each other up instead of trying to bring each other down.

If you could trade bodies with anyone, Freakier Friday-style, you’d pick…
Troye Sivan. I want to perform onstage as him so badly. Maybe Sophia can be Charli XCX…

What’s one thing that would surprise us about Sophia?
How maternal she is. She’s so caring toward her friends and her dog, Max. She’s going to be *such* a good mom someday.

What’s the last thing you texted each other?
“Ayyy, yess let’s go!” A classic Julia response.

Pick your dream karaoke duet—as your characters.
“Anything You Can Do (I Can Do Better).”

Sophia Hammons, 18 years old

Describe your character, Lily, in five words or less.
Fashionable, witty, clever, determined and British.

What’s the number one way you and Lily are similar?
We both grew up with a single dad, so to portray a character with a similar background is pretty sweet.

And the number one way you’re different?
I’m more open-minded than Lily. We both go after what we want, but I’m definitely more go-with-the-flow.

Can you tease anything about the relationship between stepsisters Lily and Harper?
They’re always wanting to one-up the other, and they keep trying to sabotage each other. But then, it sort of blows up in their faces.

How does that dynamic compare to real life?
It’s the total opposite. Julia and I mesh together pretty perfectly.

If you could trade bodies with anyone, Freakier Friday-style, you’d pick…
Jamie Lee Curtis! On set, we always joked that she runs the whole universe.

What’s one thing that would surprise us about Julia?
How fun she is. She’s always game for an adventure.

What’s the last thing you texted each other?
A screenshot of a text from my dad, where he said: “Have fun today. You definitely have a personality.” With the starry-eyed emoji.

Pick your dream karaoke duet as Sophia and Julia.
We’re already pretty good at “Iris” by the Goo Goo Dolls. I play guitar, and Julia’s insane at harmonizing.
