American actor and musician Macaulay Culkin has been in a serious relationship with his girlfriend Brenda Song for quite a while now. The 37-year-old actor has now admitted that he is ready to start a family with her.

During an appearance on The Joe Rogan Experience podcast, the Home Alone star could not stop gushing about the former Disney star. He said: "This one's a good one, so I'm probably going to put some babies in her in a little bit. I mean, we've definitely been practising."

"I'm going to have some pretty babies. She's Asian, so I'm gonna have tiny little Asian babies. It's going to be adorable — a bunch of Sean Lennon's running around the house, that's what I'm looking for," he said, referring to the son of John Lennon and Yoko Ono.

Meanwhile, Mila Kunis had recently opened up about her split from Culkin. The Black Swan actress started dating him in 2002 when she was 18. At the time, he was the world's biggest child star after almost being a decade-old in the industry and scores of blockbuster movies under his belt. However, the 34-year-old The Spy Who Dumped Me actress had parted ways with Culkin in 2010.

During the podcast Armchair Expert with Dax Shepard, Kunis took the blame for their break-up. She said: "I had a horrible, horrible breakup."

"I f**ked up. I was an a–hole in my 20s and I'll be the first to admit it. And that's something that took me a long time to come out and be like, 'Yeah, you know what, I was a d**k,' and accept it and I own it," she continued.

"And it's f**ked up what I did and it's f**ked up how I did it. When I got to be single I said, I just need to figure myself out. I genuinely need to know why I did what I did and, like, regroup myself as a human being," she shared.

"You know, it's been so long, like I feel like enough time has gone by," she said. "I think enough mutual friends have been like ... everybody kind of forgave everybody for what went down."
