Sundance doc profiles Canadian transgender YouTube star Gigi Gorgeous

Canadian transgender YouTube star Gigi Lazzarato has been extremely candid in sharing the story of her male-to-female transition with her millions of subscribers. So it's not surprising that the new documentary "Gigi Gorgeous: This is Everything," which premiered at the Sundance Film Festival Tuesday, leaves little unsaid or hidden as its 24-year-old star chronicles her "journey" from childhood, to coming out as gay, and her gender transition.
