Jackson and Culkin have been especially close lately.
Happy birthday, Macaulay Culkin!
The actor received a very special birthday message from his goddaughter, Paris Jackson, on Saturday.
"HAPPY BURFDAY I LOVE YOU," Jackson captioned a snap of herself perched on Culkin's lap on her Instagram Story. "Make 37 your B**CH."
Culkin and Jackson have been especially close lately, and got matching tattoos last month.
