The 47-year-old took to Instagram and shared the video in which the camera captures Roohi playing with the 'Caravan' when KJo interrupts and says, "Roohi beta, you don't have to resort. This caravan is a beautiful thing, but don't worry about, I will sing for you."
And Karan starts singing, "Chaudahvi Ka Chand ho..."
To which she innocently responds, "No, it pains my head!"
Karan then laughingly asks, "What? My singing is giving you a headache?"
To which Yash replies by nodding his head multiple times.
Teasing the kids, the 'Kuch Kuch Hota Hai' director tries on another song and says, "Okay, I will try one more song, "Gumm hai kisi ke pyaar mein.."
This time Yash responds laughingly and disapproves his daddy's singing, "My head's paining."
Karan then stops singing and says, "Okay, sorry!"
Taking to the captions, the 'My Name is Khan' director wrote, "No appreciation for my singing #lockdownwiththejohars."
The post on the photo-sharing platform garnered more than 3 lakh views soon after being posted. Celebrity followers were quick to respond to the video and left comments on the post.
Arjun Kapoor suggested "U just wear simple clothes" while Bhumi Pednekar left heart emoticons.
The 'Student of the Year' director is quite active on social media amid the coronavirus lockdown and has been updating his fans on his activities.
On Wednesday, Karan shared another glimpse from 'Lockdown with the Johars' in which the family explored the bathroom of their house.
