Macaulay Culkin may be private about his family life with Brenda Song, but he won't shy away from gushing about his love for her.
The two former child stars, who started quietly dating in 2017, have recently made waves over their rare but sweet outings together, and now the Home Alone actor has melted hearts over his tribute to his wife in honor of her birthday.
As the Suite Life of Zack and Cody alum rang in her 36th trip around the sun, she was treated to a cheeky birthday message from her hubby.
Macaulay took to Instagram Wednesday and shared a photo of Brenda, pictured in a bathrobe and with her hair wrapped in a towel, plus a bottle of champagne next to her.
"Happy birthday to the best friend, mother, ally, colleague, lover, and partner I could ever wish for," he endearingly wrote in his caption, declaring: "You are my reason. I love you."
He also shared a photo of a milk carton with Brenda's birthday as its expiration date, and joked: "P. S. The milk is due. Can you pick some up on your way home from work?"
Fans were then quick to take to the comments section under the post and gush over the tribute, with one writing: "Happy Birthday to the woman who brought back the light and saved our beloved Kevin McCallister," referring to Macaulay's iconic Home Alone character, as others followed suit with: "The absolute best. You both deserve the very best. Happy birthday to your love!!!" and: "They are relationship goals," as well as: "Happy Birthday Brenda, hope your day is wonderful."
