KURUPT TO PAY FOR NATINA REED'S FUNERAL!

Natina Reed's funeral is being held today in her hometown -- and TMZ has learned that rapper Kurupt, the father of her son, is covering all the expenses.

Reed -- who passed away on October 26 after she was struck by a car -- is being laid to rest at the Abundant Life Church in Lithonia, GA.

According to TMZ sources, Kurupt -- the father of Reed's 10-year-old son Tren -- is footing the bill for service as well as for the gathering after.

TMZ was told Tren will remain in Kurupt's custody -- like he has for the past four years -- and that Kurupt hopes Tren will maintain a close relationship with Reed's family.

Chilli and T-Boz from TLC, rappers Big Boi, Daz and Snoop Dogg (or whatever he's calling himself these days) are all expected to be in attendance today ... as well as members of Reed's R&B group, Blaque.

Good for him!
