On so many people speculating about their relationship, Mason shared, “It is strange. But I’ve always sort of been off the internet. I’ve always kind of kept everything to myself and been very personal. Having people speculate so much, especially having mutual friends texting me and asking…it’s wild. I’m still not used to it.”
When asked about how they’ve bonded off set, the actor said they hang out all the time.
“Not too long ago, we went to the aquarium and just walked around. She has an aquarium playlist in her AirPods. So she had one in her ear, and I had one in mine while we looked at sharks.”
“She is such an incredible actress. It’s insane to watch her,” Mason gushed about McKenna. “She is one of the most driven people I’ve ever met in my life. Every day I’m on set with her, I just want to be as good as Mckenna. She’s such a sweet person, and getting to do this movie with her is so cool.”
“Honestly, Mckenna is one of the funniest people I’ve ever met. She’ll just says some stuff, and it catches me so off guard,” he added.
In Regretting You, Mckenna will star as Clara Grant, the daughter to Allison Williams‘ Morgan Grant, and Mason will play her love interest Miller Adams.
The movie tells the story of “a shocking car wreck that takes the lives of two family members. The event unlocks a series of secrets, lies and regrets, as the people left behind can’t move forward without looking at the past,” per Deadline.
Filming wrapped at the beginning of May, and Regretting You is currently schedule to hit theaters on October 24, 2025.
