Celebrity Support for Japan's Tsunami Victims Builds

Lady Gaga

In the wake of Japan’s catastrophic earthquake and tsunami on Friday, some celebrities have wasted no time in advocating financial support to the victims.

Lady Gaga is selling personally-designed, red-and-white wristbands etched with her signature monster paw and the words “We Pray for Japan” for $5 on her website, and is also encouraging fans and followers to donate to relief efforts on the Citizen Effect web page.

Charlie Sheen, dominating the news in recent weeks with his beyond bizarre behavior, is at least using his notoriety, pledging to donate $1 from every ticket sold for his upcoming stand-up tour to the Red Cross in an effort to assist the quake-ravaged nation.

Linkin Park’s Mike Shinoda acted promptly and designed T-shirts, which feature images such as a white butterfly and the phrase “Not Alone” in a red, white and blue color scheme, to benefit his band’s Music for Relief charity.

And the tragedy obviously tugged at the heartstrings of supermodel and future “Dancing With the Stars” contestant Petra Nemcova, who survived the 2004 Indian Ocean tsunami but lost her boyfriend. The 31-year-old is now urging people to give money to her charity, the Happy Hearts Funds, which seeks to better the lives of children in regions struck by natural disasters.

A slew of other entertainers including Conan O’Brien, Katy Perry, Diddy, Chris Brown, and George Takei are also using their star status to encourage fans via Twitter to donate to the relief effort.

“Imagine... if we ALL texted REDCROSS to 90999 we'd have raised over 60million dollars for #JAPAN REFLIEF! BE THE CHANGE YOU WANT TO SEE! BE!” Perry tweeted on Sunday.

Unlike last January’s earthquake devastation in Haiti, in which everyone from Brad Pitt, Angelina Jolie and Sandra Bullock to Jennifer Aniston, George Clooney and Madonna dug deep into their own pockets to make significant monetary donations, the response from the entertainment community has been slower in buidling.

“It is definitely off to a slower start with Japan, Hollywood tends to have more of a romance with helping undeveloped countries,” Los Angeles-based publicist and commentator, Michael Levine, told FOX411’s Pop Tarts. “I suspect that in the next week a lot more stars will come forward."

“Hollywood has the power to move mountains, and after working in the world of celebrity philanthropy for 15 years, I know many stars from Eva Longoria to Leeza Gibbons are beyond willing to use their voice for the collective good of humanity,” Scott Lazerson, CEO & Founder of Mediathropic, told Pop Tarts. “Organizations like ‘Save The Children’ or ‘Convoy of Hope’ are doing real work that needs our support.”
