James Lee Williams, better known as the winner of 'RuPaul's Drag Race U.K.' season one The Vivienne, has died, with show judge Visage paying tribute to "a beacon to so many."

RuPaul has made his first public appearance since The Vivienne's death, delivering an emotional tribute at DragCon UK in London's ExCel centre on Friday. The 64-year-old drag icon appeared visibly moved as he addressed the crowd alongside fellow judge Michelle Visage.

RuPaul and longtime judge Michelle Visage joined "Drag Race" alums — including The Vivienne's "All Stars 7" sisters Jaida Essence Hall and Raja — in mourning the queen.
