And the kid was so moved by the earthquake and tsunami, his mom decided to help the youngster create products to sell around their Los Angeles neighborhood.
She tells WENN, "Me and my son, we are on the west coast still, we woke up on the morning of the earthquake and tsunami, at around six o' clock that morning, and were watching it on television. He was very affected by it and asked a lot of questions and we decided we wanted to do something together to help.
"So we actually are in the process, we're almost done... He did a watercolour of the Japanese flag and we're making shirts and totes (bags) and notecards and we're gonna sell them locally here and donate the proceeds. We're really excited about it."
Knowles is the latest celebrity to do their bit for charity to aid the Japanese relief effort - Lady Gaga, Katy Perry and Linkin' Park have all pledged profits from the sale of merchandise, clothing and wristbands to help survivors.
