Solange’s son Daniel Julez Smith is getting creative for a good cause. The six-and-a-half-year-old has designed T-shirts to benefit those affected by the devastating earthquake and tsunami that struck Japan earlier this month. His proud mom showed off his painted artwork, featuring a red circle to represent the Japanese flag.

“JULEZ FOR JAPAN! My baby boy designed a t-shirt to benefit the devastating earthquake/tsunami in Japan. All proceeds going to Peace Winds,” tweeted the “I Decided” singer. “Here is Julez working very hard on his design:) Im very proud of him.”

The T-shirts are already being sold at Julez’s school and will soon be available online to the public.
