YG Flashes Virgin Mary Tattoo On My Head

YG blessed fans and photogs in Beverly Hills Tuesday night with a glimpse of his elaborate new tattoo ... on his skull ... of the Virgin Mary.

When the rapper walked out of Mastro's Steakhouse everyone was begging for a shot of his amazing ink -- it shows Mary surrounded by the words, "No weapon formed against me shall prosper."

Despite the intricate detail of the piece ... we're told YG got the whole thing done in one 5 hour sitting.

Let us pray.
