Reality star Brandon Jenner is growing his family! Brandon, the son of Olympian Caitlyn Jenner and Linda Thompson, announced that he and his wife Cayley are expecting their third baby together. The couple’s baby is due to arrive in August.

The couple shared their exciting family new in an exclusive interview with PEOPLE. In the interview, Cayley shared that she took two pregnancy tests before sharing the news with the “Play With Me” singer. “When I went to tell Brandon that night as we were getting ready for bed he totally beat me to the punch. 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.” She revealed that the couple “conceived on Thanksgiving, which is so cute and special. I feel so grateful to get to do it all over again.”

Brandon and Cayley, who tied the knot in January 2020, welcomed twin sons in February 2020: Bo Thompson and Sam Stoker. Cayley shared that upon discussing the pregnancy for the first time, “we laid in bed and laughed hysterically thinking about how wild it would be if we had twins again.” This pregnancy, however, is just one baby. In addition to the twins he shares with Cayley, the Keeping Up with the Kardashians star has a daughter from his previous marriage to singer Leah James, 8-year-old Eva James.

Eva was the first to learn of Brandon and Cayley’s pregnancy and she found out during Christmas. “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 recalled. “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 four-year-old twins, meanwhile, can see that their mom’s belly is growing and are “really excited to be big brothers.”

Congratulations to Brandon and Cayley on the news of their third baby together!
