Whilst Esther has admitted it will take her "some time" to get used to calling her daughter - who was previously known as Bruce Jenner before undergoing a gender transition - Caitlyn, she is pleased her daughter is finally contented.

She said: "It takes some time getting used to. I've called [Caitlyn] Bruce since the day he was born. It's going to take some time, but I will adjust.

"I love her. And she's happy. That's all that matters."

Esther also admitted she was desperate to give her daughter a "big hug" when she revealed her Vanity Fair cover and praised Caitlyn's "courage".

She added to PEOPLE magazine: "It was a wonderful day. It takes so much courage to do what she's doing.

"When I first saw [Caitlyn], all I wanted to do was give her a big hug. It was such new information."

Meanwhile, Esther previously admitted there was a time where she thought Caitlyn had decided to undergo a gender transition to "make money".

She said: "I woke up one night and all I was thinking about is: Why is it necessary (for Caitlyn) to go through all these surgeries? Is this all about making money? And that was bothering me.

"He's lived a life the last 25 years - and I don't know if it was both he and Kris or mainly Kris - it seemed like their lifestyle was about money; that's why it came to my mind."
