Ashton Kutcher accidentally clipped a teenager with his car in Los Angeles on Wednesday.
The 40-year-old actor was reportedly pulling out of Sunset Bronson Studios, which has restricted view, in his black Tesla at around 3pm when he collided with 19-year-old Leo Marenghi - who was on his way to pick up some children from school - on his scooter.
Speaking to 'Entertainment Tonight', Marenghi said: "You can't really see around the corner, so he just pulled out and didn't see me.
"He hit me, and then once I fell to the ground [and] got up, I saw it was him."
The 'No Strings Attached' star - who was with his security guard - immediately stopped his car to check the youngster was unharmed before he agreed to pose for a photo with him.
Marenghi explained: "He was like, 'Are you OK?' I'm so sorry!' And I was like, 'Yeah, I'm fine, but are you Ashton Kutcher? Can I take a picture with you?'
"It felt like I just tripped and fell, and there was a security lady there, so I had her take the picture. Then that was it, and I just said, 'OK, have a good day!' "
The teenager - who suffered a grazed knee - didn't think his injuries were serious enough to exchange contact details with Ashton and has no plans to "come after him."
He said: "I think he was shocked [that photos were] all I wanted, and I was just on my way after'... After that, he's like, 'OK, you're sure you're alright?' And I was like, 'Yes.'
"Just my knee is all scraped up and sore, and my back and shoulders are a little sore, but other than that, I got lucky. I wasn't really hurt that bad."
And, despite their collision, Marenghi is still a huge fan of the actor.
He added: "Him on 'Two and a Half Men', I watched that whole season. It was really cool meeting him. Even when I was a kid, 'Cheaper By the Dozen', I just grew up being a fan."
