Lady Gaga, Stefani Joanne Angelina Germanotta

Philanthropy
Besides her career in music, Gaga has enhanced her repertoire as a philanthropist who has contributed to various charities and humanitarian works. Although declining an invitation to record a benefit song, Gaga held a concert of The Monster Ball Tour following the 2010 Haiti earthquake and dedicated it to the country's reconstruction relief fund. This concert, held at the Radio City Music Hall, New York, on January 24, 2010, donated any received revenue to the relief fund while, in addition, all profits from sales of products on Gaga's official online store on that same day were donated. Gaga announced that an estimated total of $500,000 was collected for the fund. Hours after the 2011 Tōhoku earthquake and tsunami hit Japan on March 11, 2011, Gaga tweeted a message and a link to Japan Prayer Bracelets. With the company, she designed a bracelet, with all sales revenue going to Japanese relief efforts. The bracelets raised $1.5 million (as of March 29, 2011). Performing at MTV Japan's charity show on June 25, 2011 in Makuhari Messe, Gaga appeared for the benefit of the Japan Red Cross which aids victims suffering in the aftermath of the earthquake and tsunami. However, attorney Alyson Oliver filed a lawsuit against Gaga in Detroit in June 2011, noting that the bracelet was subject to a sales tax and an extra $3.99 shipping charge was added to the price. She also believed that not all proceeds from the bracelets would go to the relief efforts, demanding a public accounting of the campaign and refunds for people who had bought the bracelet. Gaga's spokesperson called the lawsuit "meritless" and "misleading".
Gaga also contributes in the fight against HIV and AIDS with the focus upon educating young women about the risks of the disease. In collaboration with Cyndi Lauper, Gaga joined forces with MAC Cosmetics to launch a line of lipstick under their supplementary cosmetic line, Viva Glam. Titled Viva Glam Gaga and Viva Glam Cyndi for each contributor respectively, all net proceeds of the lipstick line were donated to the cosmetic company's campaign to prevent HIV and AIDS worldwide. In a press release, Gaga declared, "I don't want Viva Glam to be just a lipstick you buy to help a cause. I want it to be a reminder when you go out at night to put a condom in your purse right next to your lipstick."
With the performance of the bilingual song "Americano" from her second studio album Born This Way (2011), Gaga jumped into the debate surrounding SB 1070, Arizona's immigration law. She premiered the tune for the first time on the Guadalajara, Mexico stop of her Monster Ball tour telling the local press that she could not "stand by many of the unjust immigration laws" in the United States.
