Kieran Culkin confirmed that his brother Macaulay Culkin secretly welcomed his second baby with fiancée Brenda Song.
While speaking about his expanding family, the “Succession” star, 40, revealed that he has not yet met his nephew due to his hectic schedule with the “nightmare” of traveling with young kids.
“Well, the cousins live in Los Angeles, we live in New York,” he told Access Hollywood on Monday. “I have a 1-year-old and a 3-year-old and as busy as I am there is no getting on a plane and going.”
Kieran added, “I haven’t met No. 2 yet and they haven’t met [my] No. 2 yet either cause we just haven’t been able to figure that out.”
The “Father of the Bride” star’s revelation comes just days after Us Weekly reported that Song and Macaulay had secretly welcomed baby No. 2, a boy named Carson, sometime before Christmas.
Neither the “Home Alone” star, 42, nor the “Suite Life of Zack & Cody” alum, 34, have publicly confirmed their baby’s arrival and their reps did not immediately return Page Six’s requests for comment.
Carson joins his older brother, Dakota, 2, who was born in April 2021.
At the time, the couple said in a statement that they were “overjoyed” with the birth of their first son, whom they named after Macaulay’s late sister, Dakota, who died at 29 from injuries after she was struck by a car.
In January 2022, news broke that Song and Macaulay were engaged after four years of dating when the former Disney Channel star was spotted rocking a massive diamond ring on that finger while out and about in Beverly Hills, Calif.

Though the pair typically keep their private life mum, Song got candid last year about how motherhood has been for her while balancing her career.
“My fiancé and I are very hands-on,” she told The Cut last January. “We don’t have a nanny, but my mom has been here with us. When I was working, my mom would bring him to set so I could breastfeed and see him during the day.”
Song then urged any expecting mothers to make sure they have assistance after giving birth.
“People tell you a lot about labor and pregnancy, but not about the fourth trimester,” she explained. “To my girlfriends that are pregnant I say, make sure you have help. Because your instinct is to want to do it all and you physically can’t.”
Macaulay and Song began dating in 2017.
Before his romance with Song, the “My Girl” star dated Mila Kunis for eight years until 2010.
Song, on the other hand, was in a one-year relationship with Metro Station member Trace Cyrus in 2011.
