MTO News has been hearing rumors for MONTHS - that the facial tattoos of 22 year old rapper Tekashi 6ix9ine - are FAKE.

One prominent radio personality told MTO News last month that Tekashi's face tats were DRAWN ON. The insider explained, "Tekashi's face tats are fake. He has an artist do them with non-permanent ink every few days. If you look closely, they change from day to day. I saw him with them off."

The insider also claims that Tekashi is an "industry plant."

If you look closely - the tats do seem DIFFERENT on different days. Look at the 6-9 over his eye . . . it's not quite in the same spot as in the above pic.

But still, we had no reason to believe the accusation - until last night. Tekashi was spotted at NYC's Summer Jam concert - and he had NO FACIAL TATS. Look:

Here is the video - for those who don't believe it:

6ix9ine's real name is Daniel Hernandez, and he was born in Bushwick, Brooklyn to a Mexican mother and a Puerto Rican father. Hernandez was expelled from school in 8th grade, and did not return. In 2009, his father was murdered, which led to Hernandez working various jobs and selling marijuana in order to help his mother financially.

Hernandez began releasing rap songs in 2014. Over the next three years, he released multiple tracks and videos with titles such as “Scumlife”, “Yokai”, and “Hellsing Station”, drawing attention due to his aggressive rapping style and the use of anime as music video visuals. Many of his early songs were released by FCK THEM, a music label based in Slovakia.
