Caitlyn Jenner Has Another Grandchild on the Way

Caitlyn Jenner is expecting yet another grandbaby!

The former Olympic gold medalist will soon be welcoming another grandchild to the family, as her second-oldest son Brandon Jenner, 40, currently has another little one on the way.

Brandon and his wife Cayley announced the news during an interview with PEOPLE, sharing that their new bundle of joy is expected to arrive sometime in August.

The couple—who married in January 2020—are already parents to twin boys Bo and Sam, 4, who were born later that year. Cayley, 38, is also a step-mom to Brandon's 8-year-old daughter Eva, whom he welcomed in 2015 with his first wife, Leah James.

"We are just over the moon to be adding another baby to the family, and we can’t wait to meet him/her," Cayley told the outlet, noting that she and Brandon want to wait until the birth to find out the sex of the baby. "We didn't find out the sex of the boys—and we will keep it a surprise again this time."

The new bun in the over will be the latest addition to Caitlyn's brood of grandchildren, as just about all of her kids, including Brandon, Burt, 45, Cassandra, 43, Brody, 40 and Kylie Jenner, 26, all have children of their own. (Kendall Jenner, 28, hasn't become a mom just yet.)

Kris Jenner's ex also considers herself a grandparent to her step-children's kids, made up of KourtneyKim, Khloé and Rob Kardashian's respective offspring, which add up to 11 grandbabies, making a grand total of 23—which will soon become 24.

Earlier this month, Caitlyn appeared to be playing favorites with her grandkids while joking that Burt's son Behr might hold a special place in her heart. (Burt is also a dad to son Bodhi, 7, and daughter Goldie, 23 months.)

While celebrating Behr's 5th birthday, Caitlyn wrote on Instagram, "Happy birthday to one of the many grandkids - dare I say one of my favorite of the 23? Happy 5th Behr! Love you!"
