Jennifer Lopez is teaming with current beau Alex Rodriguez and ex-husband Marc Anthony for an NBC benefit concert aimed at helping raise money for disaster relief in the United States, Mexico and Puerto Rico.

The three-hour concert, titled "One Voice: Somos Live," will be simulcast on Telemundo and Univision beginning Saturday at 8 p.m. ET, with NBC joining in on the third hour at 10 p.m. ET. This marks the first time the two Spanish-language networks will simulcast the same programming. Other stations will be announced shortly.

Anthony will perform live from Miami, while Lopez and Rodriguez will host the Los Angeles portion of the concert. Other confirmed performers include Demi Lovato, Maroon 5, Ricky Martin, Gwen Stefani, Stevie Wonder, Coldplay's Chris Martin, Jamie Foxx, Mary J. Blige, DJ Khaled, Daddy Yankee, Magic!, Camila, Gente de Zona, Maxwell, Julia Michaels, Andra Day, Prince Royce, Nicky Jam, Romeo Santos and Alejandro Sanz.

Others confirmed to attend include Christina Aguilera, Chainsmokers, Ciara, Sean "Diddy" Combs, Vin Diesel, Bethenny Frankel, Selena Gomez, Kim Kardashian, Debra Messing, Tyler Perry, Gina Rodriguez, Zoe Saldana, Ryan Seacrest, Jada Pinkett Smith, Sofia Vergara, Jimmy Smits and Jesse Williams.

"One Voice: Somos Live" will provide food, shelter, medicine, power and communications to the areas affected by the recent natural disasters throughout the southern United States, Mexico, Puerto Rico and other affected areas in the Caribbean. Funds raised from the concert, which will also serve as a telethon, will benefit Feeding America, Save the Children, Habitat for Humanity, Unidos for Puerto Rico, United Way and UNICEF.

Those looking to give can also donate directly to the We Are One Voice GoFundMe page.

Lopez has already pledged $1 million to Puerto Rico hurricane relief efforts last month and has been working with Anthony and Rodriguez and efforts to help the area, from which her family hails.

Last month, the Big Four broadcast networks simulcast a similar concert/telethon for the Hand in Hand Hurricane Harvey benefit, which raised more than $44 million for hurricane relief efforts. Hamilton creator Lin-Manuel Miranda also recently released a charity single designed to raise funds for Puerto Rico, titled "Almost Like Praying." Miranda also teamed with Late Show host Stephen Colbert for the #PuberMe campaign, which encouraged celebrities to share embarrassing photos and videos from their puberty in an effort to raise money for the region. The campaign raised $1 million.

This is Lopez's latest collaboration with NBC, also including her starring role on cop drama Shades of Blue, her dance competition series World of Dance and her upcoming role in the network's Bye Bye Birdie Live broadcast.
