The 72-year-old appeared on Good Morning Britain on Wednesday, February 9, and discussed the latest addition to the famous family.
The former Olympian confirmed she has met Kylie's new baby. "The family is growing! Actually, Kylie had her little boy and it was announced the other day," she gushed, per Daily Mail.
Caitlyn admitted she needs to be careful when talking about her family in case she shares something she shouldn't, "But they’re great, Kylie’s great, everybody is doing good," she reportedly maintained.
Meanwhile, Caitlyn also has another grandchild on the way. "My son Burt and his wife, Val, they’re due in a month with a little girl. So I’m going for number 20 here in about a month!" she excitedly shared, per the outlet. "I can never get all the birthdays right, it's all on computer!"
Fans suspected the I Am Cait alum accidentally spilled the beans on Kylie's second pregnancy when she said she had another grandchild "in the oven" during an interview in August 2021. At the time, many assumed it was the Kylie Cosmetics founder who was pregnant again.
It was soon confirmed that Burt was expecting his third child with his wife, Valerie; however, the news didn't stop the rumor mill from suspecting Kylie had another little one on the way.
In September, a source told Heat World Kylie was furious with Caitlyn because she initially wanted to keep her pregnancy under wraps, as she had previously done ahead of her first child's arrival.
"What’s worse is that Cait’s just laughing it off and telling Kylie to get over herself," the source reportedly revealed. "Kylie has had her issues with Cait in the past, but this is a real low point."
Kylie and the rapper have yet to announce their new bundle of joy's name.
