Travis Scott's Rainbow Grill Only Cost Him $25,000

Travis Scott has more colors coming out of his mouth than a kid downing a bag of Skittles ... thanks to his very unique tricked out grill.

We found out Travis enlisted celeb grill master Johnny Dang to whip up his 18 carat gold piece which is filled with 10 carat pink, brown, blue and white diamonds! Travis plans to unveil his multi-colored mouth during his upcoming Anti World Tour dates with Rihanna.

Travis dropped $25,000 for the grill ... which had to be shipped overnight for a show this week.

Mouth stunna!
