Shakira and Juan Luis Guerra have joined an ever-growing list of Latin artists donating money and supplies and organizing fundraisers for victims of Haiti’s earthquake. Shakira's Barefoot Foundation will partner with nonprofit firm Architecture for Humanity to build a school in Haiti. Philanthropist Howard Buffett, who serves on the board of Shakira's foundation, will fund the school's food program. The Barefoot Foundation will partner with non-governmental groups to provide education, water and sanitation for the school, modeled on those Shakira has founded in Colombia for children displaced by violence.

Dominican star Juan Luis Guerra is planning a concert in April or May to raise funds to build a children’s hospital in neighboring Haiti. The concert, the date of which hasn’t been set yet, will take place at Santo Domingo’s Felix Sanchez stadium and will benefit the Sur Futuro Foundation’s effort to build the hospital. According to a press release from Guerra's label Capitol Latin, discussions are underway with “international artists” to perform at the concert.

Meanwhile, the Univision Network's long-running variety show, "Sabado Gigante," will hold a star-studded, four-hour telethon tomorrow, "Unidos por Haiti."

Shakira, Ricky Martin, Alejandra Guzman, Chayanne, Daddy Yankee, David Bisbal, Gloria Estefan, Graciela Beltran, Luis Fonsi, Natalia of la Quinta Estacion, Olga Tanon, Pee Wee, Thalia and Willy Chirino are among the artists confirmed to perform during the fundraiser for the American Red Cross' earthquake relief efforts.

The special airs at 7 pm ET/PT and will be simulcast on Univision's Galavision cable network. The show will air from the "Sabado Gigante" studios in Miami but will feature live segments from Los Angeles, New York, Washington D.C., Puerto Rico, the Dominican Republic and Haiti. The special will be broadcast in 10 Latin American countries; Univision Radio talent will also be on hand during the broadcast to encourage donations from viewers.

Univision's multi-platform effort has included PSA's and coverage of relief efforts on its TV and radio properties as well as the creation of a dedicated Web site, univisionhaiti.com.
