With the debut of Caitlyn Jenner on the cover of Vanity Fair's July issue Monday, photographed by Annie Leibovitz, Bruce Jenner's gender transition is complete. And Twitter went crazy, with commenters offering support, finding resemblances between Caitlyn and Jessica Lange, and joking that Caitlyn doesn't start with a "K."

In Diane Sawyer's April interview with Jenner, "he," "his" and "Bruce" were still used, by Jenner's request, as the  transition wasn't yet complete and Jenner's new name hadn't yet been chosen. So the coming out on Vanity Fair is a twofold change -- both visual and linguistic. The ABC "20/20" interview garnered  17.1 million viewers, according to Deadline.

Transgender visibility has risen in the past few years, but perhaps no figure has catalyzed the coverage as much as Caitlyn Jenner, 65, has. If Jenner's interview with Sawyer was a watershed moment for transgender and gender queer subjects, this cover is a close second. 

The issue is on newsstands June 9, with an accompanying inside interview of Jenner by Pulitzer Prize–winning contributing editor and "Friday Night Lights" author Buzz Bissinger.
