Macaulay Culkin and his fiancée Brenda Song have welcomed their second child together, the Home Alone star's brother has confirmed.
Last week it was rumoured the Home Alone actor, 42, and his former Disney Channel star fiancée, 34, had become parents once again.
A source claimed the pair welcomed their second child three months ago after Brenda gave birth to Dakota in April 2021.
It's been claimed Brenda gave birth to a son, whom they called Carson, around Christmas.
Now, Macaulay's brother Kieran Culkin, 40 - who is best known for his role in TV series Succession - has confirmed the happy news.

The actor is a father to his own children with wife Jazz Charton, 34; a daughter called Kinsey Sioux, three, and son Wilder Wolf, one.
In an interview with Access Hollywood, Kieran explained: "Well, the cousins live in Los Angeles, we live in New York.
"I have a one-year-old and a three-year-old and as busy as I am, there's just no like getting on a plane and going, and same with them."
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."
He explained his children's young age is putting him off making the lengthy journey across the country to meet up with his brother.
The actor said: "We have a one-and-a-half-year-old, the first go around we did that, she was about 19 months, I think - nightmare.
"She's three-and-a-half now - now she's good on a plane - but our son is about a year-and-a-half, so we're not getting him on a plane anytime soon. It's just a nightmare."
Last week, baby number two's arrival was revealed to US Weekly by a source close to Brenda and Macaulay.
Last year they also became engaged and have been making plans to tie the knot in the near future after being romantically linked for five years.

And they also revealed that the pair were already planning another addition to their family.
They are said to be "hands-on" parents, with Brenda saying: "My fiancé and I are very hands-on. We don't have a nanny, but my mom has been here with us since my son was born.
"When I was working, my mom would bring [my son] to set so I could breastfeed and see him during the day."
