HERE is how Caitlyn Jenner decided on her name!

New York - Choosing between a "C" and a "K" for her new name was no small task for Caitlyn Jenner, considering her famous K-heavy family of Kardashians.

In new material from Jenner's Vanity Fair interview, she said coming up with a new name had her looking in a variety of places.

"It's one of the hardest things in life - choosing your own name," she said. "One way she attempted to come up with ideas was by watching the Miss America pageant."

She also liked Heather and Cathy, but Caitlyn was a front-runner when her assistant, Rhonda, independently suggested it, Jenner said.

She responded: "I love that name, too!" and the coincidence helped seal the deal, according to Vanity Fair.

But Jenner went back and forth about how it would be spelled, deciding it was best to break the Kardashian tradition.

Jenner, formerly known as Bruce, was married to Kris Jenner and step-parent to the Kardashian clan. Her daughters are also named K-names — Kylie and Kendall.

Vanity Fair on Monday released the first photo of newly transitioned Bruce Jenner.

Caitlyn, as she will now be known, has bravely graced the cover of the magazine’s latest issue and she looks absolutely flawless.

The former athlete is currently transitioning to a female and had a photoshoot with world famous photographer Annie Leibovitz to show off her new image.

This comes after it was revealed the Keeping Up With the Kardashians star has undergone surgery to make her face more feminine, BangShowBiz reported.

Caitlyn - who was previously married to Kardashian matriarch Kris Jenner - only confirmed her plans to undergo gender reassignment surgery last month when she recorded a special interview with Diane Sawyer, she has reportedly already had a lot of work done and is hoping to be living as a woman within months, with the process being documented in her own reality show.

She has also joined Twitter as @Caitlyn_Jenner and tweeted; "I'm so happy after such a long struggle to be living my true self. Welcome to the world Caitlyn. Can't wait for you to get to know her/me."
