Brenda Song doesn't have to take on life alone.
The Suite Life of Zack & Cody alum explained exactly why her relationship with Macaulay Culkin remains so suite after all these years.
According to Brenda, the secret for the couple—who got engaged over two years ago—is "showing up" for one another.
"I know that everything is taken care of," she exclusively told E! News' Francesca Amiker at the premiere of The Last Showgirl at the Toronto International Film Festival Sept. 6. "I never have to worry about anything."
In fact, since realizing the Home Alone star was the one for her, Brenda explained, "My life became so stress-free in a way, because I have someone that I trust, that I know who knows me. And to me, that’s supportive."
And Macaulay was by her side doing just that on the red carpet at TIFF, showing his support for her new movie costarring Pamela Anderson and Jamie Lee Curtis.
"He does not like to do these carpets," Brenda revealed, "and here he is."
But it's not just movie premieres that the former child stars tackle together. They're also parents to son Dakota Song Culkin, 3, and a 2-year-old boy whose name hasn't been revealed. And one of her favorite parts of motherhood is seeing how their sons have taken after them while also developing personalities of their own.
"It’s funny, they’re a mixture of both—like truly, straight down the middle," the 36-year-old shared. "You can find a little bit of both of us in each of them."
So, will her kids be following in their parents' footsteps in Hollywood?
"I hope not," Brenda joked. "They’re 2 and 3, so they’re just playing pretend and being little boys."
What's clear is that Macaulay feels the same way about the family they've created, confessing during his Hollywood Walk of Fame ceremony in December that Brenda is his "everything."
"You're my champion. You're the only person happier for me today than I am," he continued. "You're not only the best woman I've ever known, you're the best person I've ever known. You've given me all my purpose. You've given me family."
