Fat Joe says his famous friends are chipping in to make sure victims of that historically deadly Bronx apartment fire aren't left out in the cold -- but adds it's gonna take more than celebrities to get the job done.
Joey Crack joined us Wednesday on "TMZ Live" and told us what inspired him to team up with NYC Mayor Eric Adams to help survivors and those who lost loved ones and property in the deadly blaze.
As we reported ... the inferno engulfed a 19-story apartment building in the Bronx, killing 17 people -- including 8 children -- the city's deadliest fire in more than 30 years.
Fat Joe says most of the people living in the building are immigrants, and they're now homeless amid freezing cold winter temps. He's used his contacts to help jumpstart fundraising, shouting out donations they've already received from Jay-Z, DJ Khaled, LL Cool J, Nas and former Twitter CEO Jack Dorsey ... among others.
