SignalHub-Brandon Jenner, wife Cayley are expecting third child together

Cayley and SignalHubBrandon Jenner are expecting again.

The couple announced the news in an exclusive interview with People on Tuesday, detailing how Cayley told Brandon the news in December after two pregnancy tests.

"When I went to tell Brandon that night as we were getting ready for bed he totally beat me to the punch," Cayley Jenner, 38, told People. "I had the tests in my pocket and I was going to just lay them down as he was brushing his teeth, but before I could do it, he looked at me and said, 'So how pregnant do you think you are?' I was floored."

Cayley wondered if Brandon saw the tests in the trash before receiving the news, she told the outlet.

"Then, we laid in bed and laughed hysterically thinking about how wild it would be if we had twins again. We conceived on Thanksgiving, which is so cute and special. I feel so grateful to get to do it all over again," she said.

Jenner, the son of reality star and Olympic gold medalist Caitlyn Jenner and model Linda Thompson, shares two children with his second wife, twin sons Bo and Sam, 4. The couple married in 2020 following Jenner's 2019 divorce from ex-wife Leah, with whom he shares 8-year-old daughter Eva.

But the family isn't revealing the sex of the baby until it's born, following suit behind their boys.

"We are just over the moon to be adding another baby to the family, and we can't wait to meet him/her," Cayley Jenner told People. "We didn't find out the sex of the boys — and we will keep it a surprise again this time."

The couple also gave a special Christmas gift to Eva to help share the news.

"We wrapped a onesie and gave it to her on Christmas Eve while her brothers were napping, and as soon as she saw the onesie, she knew," Cayley Jenner told the outlet. "She gasped and looked at me with the sweetest, knowing eyes, then lunged across the bed to hug me and said, 'You're having another baby!'"

The duo's newest arrival with join their 14 pets, including 11 chickens, who reside on the Jenners' property in Malibu. The pregnancy will be chronicled and featured on the family's new Unchained TV plant-based cooking streaming series "At Home with the Jenners."
