Saweetie & Jadon Sancho

Saweetie and Manchester United star Jadon Sancho have been a rumored couple for months ... and their recent trip to a renowned tattoo shop possibly reveals their bond goes BEYOND skin deep!!!

TMZ Hip Hop obtained images of Saweetie and Jadon hitting up The Apollo Tattoo & Piercing Studio in Santa Monica this summer ... where the heavily tatted athlete expanded his art physique -- by adding Saweetie's middle name, Qiava, on his neck behind the left ear.

The tat has a nice, stylish flair in cursive ... we know das right!!! 💅🏼
