Bam Margera is the proud owner of some new ink, this time it's in honor of his son -- and the guy put it right on his face for all to see.
Gray Wake, Bam's tattoo artist, tells TMZ ... the former "Jackass" star came with a friend into Tribal Roots Tattoo Studio last week in Escondido, CA -- looking to grab a new tat.
He says he recognized Bam instantly because he grew up watching the series, but didn't know ahead of time he was coming in.
