Caitlyn Jenner discussed how important it was for her to be cover girl on Vanity Fair, particularly to those who were critical of her decision to transition gender, on reality show I'm A Celebrity...Get Me Out Of Here.

The former Olympian gold medalist discussed the momentous occasion in June 2015 and described it as: 
"For me this was a big f*** you to the millions and millions of people out there that had said terrible things about me. And it just came out and it just shocked them."

The 70-year-old said she had felt it was "extraordinarily important" that she tried to make an impact on social media and the direct message to the "millions" who had said "terrible things" about her.

She said: "As soon as the cover of Vanity Fair broke, in the next four hours and one minute, it broke the world record for the fastest to one million followers on Twitter."

Discussing her transition with Jacqueline Jossa, the reality star said; "Over many, many, years I had a lot (of surgery) but then near the end it went pretty quickly because you can do your face and your chest all at the same time which they did. Actually for guys if they go on oestrogen they will grow boobs OK."

"And in my case I was on oestrogen back in the 80s and had a little 36/38B and then I met Kris and had them chopped off.

And then the second time round 25 years later I was back on oestrogen obviously and they came back - some but not much.

So I really had to have them done so it is kind of past the point of no return." revealed Caitlyn.

The latest episode also saw Jossa and Ian Wright face a stomach-churning trial in which they had to clamber through tunnels filled with crickets, worms, toads and spiders.
