While most of us have our children trained to call us 'Mum' or 'Dad' (or something along those lines), it's not uncommon for our kids to accidentally slip up and call us by our real names.
John Legend's wife Chrissy Teigen just so happened to be filming at the perfect time as their daughter Luna was holding their new puppy, Petey.
As Luna carried her new poodle to her dad, she said, "John, would you like to hold her?"
Chrissy burst into laughter from behind the camera as John gave his wife that classic annoyed-parent glance.
"I'm not John," he said with an incredulous smile. "I'm your dad."
