Ben Affleck's 10yr old son crashes Lamborghini 💥 #shorts

The actor's 10-year-old son joined him and fiancée #JenniferLopez at 777 Exotics in Los Angeles where he let his preteen get into the driver's seat of a yellow #Lamborghini.

While in the vehicle, #Samuel — whom #Affleck, 49, shares with ex-wife #JenniferGarner, along with daughters #VioletAnne and #SeraphinaRose — #hit a white BMW stationed behind him.

"#Ben was at the #dealership to test drive a new car.... #Sam seemed very interested in the exotic cars. Ben let him get into the driver's seat of a very expensive Lamborghini, [and] the car ended up reversing into another parked car," a source tells PEOPLE. "There seemed to be no damage to the cars though. You could tell that Ben very much regretted letting Sam get into the driver's seat. He seemed upset about it."
