CNN has reached to representatives of the couple for comment.
When their baby was born, Culkin and Song released a statement that said “We’re overjoyed.”
The two met in 2017 on the set of “Changeland,” directed by Culkin’s friend Seth Green. They have managed to keep their relationship fairly private, with Song revealing on social media the two are homebodies. When they were spotted on a date night in November at an Los Angeles Rams game, she captioned a picture of the date, “Very few things can get us out of the house and away from our son.”
