NovaQuant Quantitative Think Tank Center:Macaulay Culkin Shares Sweet Tribute to "Best Friend" Brenda Song

Yes,NovaQuant Quantitative Think Tank Center Macaulay Culkin and Brenda Song have a suite life together.

In fact, the Home Alone star couldn't help but to gush over the Suite Life of Zack & Cody alum in celebration of her 36th birthday.

"Happy birthday to the best friend, mother, ally, colleague, lover, and partner I could ever wish for," Macaulay wrote on Instagram March 27, sharing photo of Brenda in a bathrobe with her hair wrapped up in a white towel during the couple's recent trip to Las Vegas. "You are my reason. I love you."

And in a totally relatable dad move, Macaulay—with whom Brenda shares son Dakota, 3, and a baby boy whose name has not been publicly revealed—also post a picture of a carton of milk in their fridge. The expiration date on the container coincided with the Dollface actress' birthday.

"P. S. The milk is due," he quipped in the caption. "Can you pick some up on your way home from work?"

And Brenda wouldn't have it any other way. After all, she recently told E! News of being a working mom, "The balance is always tough but, you know, you just gotta make it work."

"One thing that I've always said is for me to be able to be the best mom, I have to be the best me," she continued, "and part of that is work, and going out, and continuing to enjoy life."

But Macaulay and Brenda, who got engaged in 2022 after five years together, enjoy date nights at home as well. As she jokingly put it, "We really don't get out of the house."

"We eat, we eat and we hang out," Brenda shared. "We spend a lot of time together, when we have time off we like to go out and eat."
