Caitlyn Jenner Reveals She Has Another Grandchild on the Way: 'Found That Out the Other Day'

Caitlyn Jenner said while campaigning at a California toy store that she has a 19th grandchild "in the oven"

Caitlyn Jenner says her famous family is expecting a new addition!

The Keeping Up with the Kardashians alum, 71, revealed that she has another grandchild on the way, a comment she made Thursday while visiting the Toy Store in Quincy, California, on the campaign trail, which was live-streamed on the small business's Facebook page.

(Caitlyn is running to replace current Gov. Gavin Newsom, a Democrat, in a special election next month after a Republican-led effort gathered enough signatures across the state to force a recall vote.)

"Eighteen grandchildren. I keep telling the girls — they're not too excited about this, but — I wanna go for 30," Caitlyn says in the video. "Thirty grandchildren. It's a round number. I just found out the other day that I have another one in the oven. Yes, I found that out the other day. So that's 19, so we only got 10 to go."

The Olympic gold medalist did not say which of her kids were expecting. Caitlyn has six adult children: Kylie, Kendall, Brody, Brandon, Cassandra and Burt, as well as stepchildren with ex-wife Kris Jenner: Kourtney, Kim, Khloé and Rob.

Kim Kardashian West has four children; Kourtney Kardashian has three; Brandon Jenner has three; Cassandra Jenner has three; Burt Jenner has two; Kylie Jenner has one; Khloé Kardashian has one; and Robert Kardashian has one.

While Jenner didn't confirm, later on Friday, PEOPLE confirmed that Kylie, 24, is pregnant, expecting her second baby with Travis Scott.

In May, Caitlyn said on CBS This Morning that when it came to her campaign, she did not expect her celebrity children to be vocal about her political aspiration.

"I did speak with all my children and I said, 'Hey, I don't want one tweet, I don't want you—this is my deal,' " she said at the time.

"You told them not to be involved?" asked host Anthony Mason, to which Caitlyn replied, "Yes. Not to be involved whatsoever. ... I said if anybody asks any questions in the media — because obviously they are in the media — I just said, say 'no comment,' address your comment to me."

A source told PEOPLE earlier this year that the famous family wants Caitlyn "happy," regardless of whether they agree with her politics: "There have always been differing political opinions within the family. But everyone can agree on one thing: They want Caitlyn to be happy."
