What a day. We opened with news of a new Kardashian baby, now we're ending it with this: Bruce Jenner completes his transformation into Caitlyn on the cover of the latest issue of Vanity Fair.

Shot by Annie Leibovitz, Caitlyn wears a strapless body suit on the seminal cover, which was unveiled today on the magazine's website.

#CallMeCaitlyn - the issue's cover line - started trending globally almost instantly. Caitlyn herself is, naturally, on Twitter already (along with a few pretenders).

In the accompanying interview, Jenner speaks movingly about her journey to VF contributing editor Buzz Bissinger.

'If I was lying on my deathbed and I had kept this secret and never ever did anything about it, I would be lying there saying, "You just blew your entire life,"' he says.

The issue hits newsstands on 9 June.
