Fat Joe’s got hart… And, he’s ready to share it with the world.

The 50-year-old Puerto Rican and Cuban American rapper, whose real name Joseph Antonio Cartagena, will take part in the MDA Kevin Hart Kids Telethon, the upcoming two-hour special hosted by Hart that reimagines the Muscular Dystrophy Association’s annual variety show fundraiser.

Fat Joe joins a lineup of talent additions that includes Don Cheadle, Common, Cindy Crawford, Whitney Cummings, Stephen Curry, Zachary Levi and Kelly Rowland.

The special, which will benefit the MDA and Help From the Hart Charity, streams live on Saturday from 8:00 – 10:00 p.m. ET on Hart’s LOL Network and its digital platforms YouTube and Pluto TV, as well as on TikTok, Triller and Twitch.

SiriusXM will air an encore of the show on its Laugh Out Loud Radio channel on October 26 at 4:00 pm ET and again the next day at 10:00 am ET.

The telethon will feature entertainment, comedy, musical performances and MDA’s Let’s Play For a Cure gaming elements, a gaming stream hosted by Zedd running simultaneously. A Telethon Showcase to celebrate the members of the neuromuscular community and hosted by Nancy O’Dell and Jann Carl will follow the two-hour main show. It will stream on the MDA’s Facebook page.

As a warmup, an MDA-hosted online auction on CharityBuzz featuring items from Serena Williams, Curry and others launches Friday at mda.org/telethon.

The latest talent additions to the lineup join previously announced guests including Garcelle Beauvais, Aloe Blacc, Jack Black, Usain Bolt, Bryan Cranston, Adam Devine, Josh Gad, Liz Gillies, Aldis Hodge, Edwin Hodge, Michael B. Jordan, DJ Khaled, Daniel Levy, Loni Love, Leslie Mann, Jillian Mercado, Robin Thicke, Gabrielle Union Wade and John David Washington.
