Caitlyn Jenner was supposed to be stumping for governor of California in Plumas County Thursday and Friday, while viewing devastation left by the Dixie Fire, but instead, the candidate in the contentious Sept. 14 recall election made a stray comment Thursday that focused attention on growing internet speculation that her famous daughter, Kylie Jenner, is pregnant with baby No. 2.

While visiting a children’s toy and clothing boutique in the small town of Quincy, the reality TV star and ex-Olympian opened up about her 18 grandchildren, TMZ reported. She joked that she wanted 30 grandchildren for the evenness of the number before confirming she will soon have 19 grandchildren, as one is “in the oven,” TMZ said.

To be clear, the “I Am Cait” star has six adult children, so presumably any one of them could be welcoming a new baby, but there’s a theory, particularly on TikTok, that Kylie Jenner is the one who is secretly pregnant.

Internet sleuths have picked through photos and videos that the Kylie Cosmetics mogul has shared recently, including of her 24th birthday on Aug. 10, Yahoo reported. One TikTok user in particular, @carolinecaresalot, went viral with a video she posted Aug. 11, explaining why she thinks Jenner is secretly pregnant.

Her main evidence has to do with videos and photos shared by Jenner and her friends for her birthday gathering. First she said it was odd that the party was a small, intimate gathering, rather than the usual spectacle Jenner is known for, which would provide days of Instagram content. While the low-key party could be because of the pandemic, @carolinecaresalot argued that none of Jenner’s guests shared photos of her at the party. Instead, all the party posts were of the food, drinks or of other guests.

@carolinecaresalot also argued that a photo Jenner shared of herself on her birthday, in a body-hugging green dress and with a flat stomach, was an old photo, based on her fingernails. She furthermore contended that any recent photos Jenner has posted of herself in skimpy bikinis also were shot some time ago.

TMZ added that the rumor mill is spinning about Jenner being pregnant because she appears to be back together with Travis Scott, her on-again, off-again rapper boyfriend and the father of her 3-year-old daughter, Stormi Webster. TMZ noted that the “Keeping Up WIth the Kardashians” star was super-secretive about being pregnant with Stormi.

But, of course, any of Caitlyn Jenner’s other children could be expecting. Caitlyn Jenner, 71, has children from all three marriages. Jenner’s first marriage to Chrystie Scott produced son Burt and daughter Cassandra. Caitlyn Jenner and her second wife, Linda Thompson, share sons Brandon and Brody. Most famously, Caitlyn Jenner’s third marriage, to reality TV mega-manager Kris Jenner, produced Kylie and her older sister, supermodel Kendall Jenner.

Meanwhile, Caitlyn Jenner was expected to wrap up her visit to Plumas County Friday. The Plumas News reported that she was visiting the area to view the devastation of the Dixie Fire firsthand and to learn more about the timber industry.

The fire has burned nearly 700,000 acres and destroyed 1,224 structures, including 659 homes, but is only about 35 percent contained. The fire still threatens another 16,085 structures in four counties and sites in Lassen Volcanic National Park.

Caitlyn Jenner’s itinerary includes visiting the fire camp at the fairgrounds, participating in a round table meeting with local officials, stopping at local businesses, and touring the small historic town of Greenville, which was decimated by the fire.
