The 65-year-old former Olympian - who was known as Bruce Jenner before undergoing a gender transition - is reportedly allowing her daughters Kendall, Kylie and Cassandra, sons Burt, Brody and Brandon and stepchildren Kim, Khloe, Kourtney and Rob Kardashian, to continue referring to her as their father for the time being.

A source told PEOPLE magazine: "(Caitlyn) spoke to each of the kids separately and told them to take their time in getting used to this. She would prefer not to be called 'Bruce,' but told the kids that they could still call her 'Dad,' at least for now.

"Caitlyn has been really understanding that it doesn't come naturally for anyone. No one expects this change to happen overnight. If one of the boys slips up, it's not a big deal."

Meanwhile, Caitlyn's mother has admitted she will find it "hard" at first to refer to the star by her new name.

Esther 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."
