While most of the news buzzing these days is around Caitlyn Jenner’s ex-stepdaughter, Kim Kardashian (who may be retiring from public life!), as well as Cait’s own daughters, Kylie and Kendall, other family members (the ones who don’t spend their lives in front of the cameras) have plenty to celebrate as well. Why? Well, the Jenner family just got even bigger! That’s right Kendall and Kylie are aunts again and Caitlyn is a grandma again as her daughter, Cassandra Jenner Marino, gave birth to a baby boy this week.

35-year-old Cassandra is Caitlyn’s daughter from her first marriage to Chrystie Crownover, and though we don’t often hear about the I Am Cait star’s elder daughter, all the focus is on Cassandra and her newborn son.

“He made it! One day before his due date and on Mike’s dad’s birthday. 8lb 13oz 22 inches long,” Cassandra wrote on Instagram. “I am elated and exhausted but a super happy non-pregnant mama :)” Cassandra wrote on Instagram before deleting the pics. She also posted a shot of her daughters, Isabella and Francesca, saying, “Proud big sisters. They are over the MOON.”

This is the second grandchild for Caitlyn this year, as her son 37-year-old Burt also welcomed a baby boy named Bodhi into the family back in July.

Congratulations, Jenners!
