Caitlyn Jenner has revealed she has to be "very careful" when talking about daughter Kylie's new baby, as she claims there is "secrets in the family".
The former Olympian, 72, made an appearance on Capital Breakfast earlier today to chat with hosts Roman Kemp, Sian Welby and Sonny Jay.
But Caitlyn raised eyebrows during her interview as she said there are "a lot of secrets" in the Kardashian-Jenner family.
Caitlyn got into hot water with her youngest child after prematurely revealing her pregnancy last year.
Kylie, 24, welcomed her second child with partner Travis Scott earlier this month and revealed the news via Instagram.
But her pregnancy reveal appeared to be ruined last year when Caitlyn let slip the happy news in an interview.
It is reported that she wanted to keep the pregnancy a secret until she gave birth - similar to her famous first pregnancy and birth announcement in 2018.
On the radio, Roman asked: "Caitlyn, I texted you the other day, you’ve become a grandparent once again because of Kylie’s newborn!"
Joking with the host, Caitlyn replied: "Oh you have to bring my age up again, right?"
Roman playfully said: "Yes unfortunately."
Caitlyn added: "Alright, that’s it, ok, I’m old! I have lots of kids! No actually I had grandchild number 19."
Surprised, Roman said: "Wow! Grandchild number 19, I mean, from us congratulations! Have you met the newborn yet?"
Caitlyn responded: "Oh yes, and, um yeah. Yes. We don’t have a name but it is a boy. There’s a lot of secrets in my family, I have to be very, very careful. No, Kylie, she did a great job. Yeah, I have to watch out when I talk about that."
She concluded: "But yeah, we got one more, number 19 in the family. And Roman, we got another one in the oven! A month away, my son Burt and Val, they’re having a little girl and her due date’s in about a month. So that’ll be number 20."
Kylie announced the birth of her second child on Monday.
The Keeping Up With The Kardashians star shared a sweet black and white snap on Instagram on Sunday alongside the caption: "2/2/22".
The photo appeared to be Kylie and Travis' four-year-old daughter Stormi clasping her new little brother's wrist in an adorable sign of affection.
She also included a blue heart emoji in the post as fans and famous pals flocked to the comments section to send congratulatory messages.
No name has yet been announced for the youngster.
