American celebrities are calling on their fans to come together and dig deep into heir pockets to help raise funds for victims of the earthquake and tsunami with Lady Gaga spearheading the campaign.

In just 48 hours more than $250,000 has been raised after the eccentric Lady Gaga announced on Monday her plans to raise money through selling white and red wristbands with the message “We Pray for Japan” via her own website.

Lady Gaga has thanked her fans for ordering over 50,000 wrist bands which are being sold for $5 each by taking to twitter.

She said on Wednesday: “Monsters: in just 48 hours you've raised a quarter of a million dollars for Japan Relief.”

While Lady Gaga has launched a wrist band rockers Linkin Park have started to take orders from fans for special T-shirts though their website.

The shirts have been designed by Mike Shinoda from the band, his father is Japanese-American and 100% of the proceeds raised from the sale of the shirts will be donated to the Music for relief fund which will help the victims of the disaster.

The Linkin Park T-shirt costs $25 and features an origami butterfly with the words “Not Alone” against a black background.

Experts have worked out that if every Lady Gaga follower on Twitter bought a wrist band and every Linkin Park follower bought a T-shirt then a massive $47 million would be raised for Japan.
