The 'Drag Race' host is being featured alongside other fashion icons in the show's latest installment.

Tracing his roots all the way back to 1870, Gates reveals that one of Posen's great-great-great-grandparents was a tailor. "A trade he likely learned from his father and then passed down to his son," Gates elaborates. "There's a tremendous legacy of craftsmanship running through your family."

"It's powerful," Posen agrees, as he soaks in the information. "It's powerful stuff. ... So much of history gets erased, and I think obviously genetics don't."
