Snoop Lion -- I'm Donating to 6-Year-Old's Funeral Too ... 'We Need to Come Together'

Snoop Lion TO THE RESCUE -- the rapper just announced he's also giving money to help cover the funeral costs for a 6-year-old girl who was fatally shot last weekend in California.

Rapper The Game has already donated $10,000 to help pay the funeral bills for 6-year-old Tiana Ricks -- who was shot and killed when two men approached her family's Moreno Valley home and opened fire -- but sadly, Tiana's mom said the money wasn't enough to cover all the bills.

Snoop's rep wouldn't say exactly how much he donated, but sources close to Tiana's family tell TMZ the amount was $2,000.

Snoop has released a statement about the shooting, saying, "Little 6-year-old girls are not supposed to die from a gunshot. But it keeps happening ... Too many tears are being shed, too many young lives are being cut short. We need to come together to change this."

FYI, Snoop has Crip ties and Game openly identifies with the Bloods (a rival gang) ... so Snoop's really not kidding about the "coming together" stuff.

Snoop added, "Beautiful Tiana loved to play the piano -- she had a whole life ahead of her which she should have been filled with love and music."
