Gwen Stefani donated $1,000,000 to Save the Children's Japan Earthquake-Tsunami Children in Emergency Fund to help in the relief and recovery effort, according to Hollywood Reporter.

"I've been inspired by Japan for many years and have a true love, appreciation and respect for the Japanese people and their culture," the singer said in a statement.

"The disaster in Japan is beyond heartbreaking and I want to do anything I can to help. I would never be able to make a gesture like this without the love and support of all the fans over all these years," Stefani added.

A limited edition Harajuku Lovers T-shirt designed by Stefani will be available next week through www.nodoubt.com, with all proceeds going to the relief efforts in Japan.

A charity auction is also being organized where fans can bid on the chance to join the singer at a special fundraiser in Los Angeles.
