However, Esther says it may take her a while to stop using male pronouns or Caitlyn's birth name. "I still have to call him Bruce. His father and I named him that," she tells Access Hollywood. "It's going to be a struggle for me to get used to the change, but happily so. I'm very happy for him — or her!"

Caitlyn, for her part, tells Vanity Fair that she too needs to get used to her new name. "I don't really get hung up [if people use male pronouns or her former name]," she says. "A guy came in the other day and I was fully dressed — it's just habit, I said, 'Hi, Bruce here,' and I went, Oh f---, it ain't Bruce, I was screwing up doing it."

The Vanity Fair issue featuring Caitlyn Jenner will be available on newsstands on June 9.
