Gosling told DeGeneres that his love of street art began years ago, explaining, "When I was a younger man I had a fantasy of getting into the graffiti world. I was living downtown, and I heard that if you tag over someone else's that that's how you start a battle. So I did this for a few months and no one ever bothered to battle with me because I was so bad at it."
However, it seems some troublemaker is trying to start a battle with his daughter, and Gosling couldn't be more excited to get into the fray.
"Some kid has been erasing her name and writing their name over it. So now I'm in a proper tagging battle," Gosling said, trying to temper his excitement. "And this kid has access to an unfair amount of chalk."
"I'm trying to explain to my little girl that this is [unacceptable.]," he recounted. "She doesn't care. She's like, 'Well let's just chalk anywhere else,' and I'm like, 'No, no. They're disrespecting your mother. Because, she gave you this name and they're erasing it.' So the only way to really get back at them is to erase their name. And not disrespect their mother, but definitely put her on notice. Because I think she's the chalk supplier."
The 35-year-old leading man admitted that it's easy to go overboard when getting involved in your kids' feuds. "You've got to be careful when you're trying to teach your kid what a reasonable amount of vengeance is," Gosling explained.
"She's adorable,” DeGeneres jokingly gushed. "She's so precious. She looks just like you."
