But suddenly, a toddler bursts into the room in a bright yellow top and performs a comical dance behind him.
His focus remains entirely on the camera as he attempts to blindly hand off his child, who is clearly curious as to who Mr Kelly is talking with.
And his parental problems soon double as a baby also excitedly makes his way into the room in a stroller.
To complete the farce, a female figure - either their mother or a nanny - comes skidding through the threshold.
She grabs the two youngsters and attempts to drag them out of the door, but one of them can be heard wailing and the baby's stroller suddenly won't fit back through the door.
Eventually, she manages to get them both out, and the interview continues.
When the interview finishes, the broadcaster says:The hilarious footage was tweeted by BBC producer Julia MacFarlane, who promptly deleted it 20 minutes later.
She wrote: 'When the kids interrupt you in the middle of live TV...A lovely moment and masterfully handled by our guest this morning on South Korea'.
