It’s a boy! Caitlyn Jenners daughter Cassandra “Casey” Jenner Marino welcomed her third child with husband Mark Marino, a source confirms to Us Weekly.

"She had a beautiful baby boy named Luke. He came one day before his due date,” the insider tells Us.

According to Entertainment Tonight, the I Am Cait star’s daughter shared a photo of the newborn on her private Instagram account. “I am elated and exhausted but a super happy non-pregnant mama :),” she wrote, adding that her baby boy weighed 8 pounds, 13 ounces, and measured 22 inches long.

The 35-year-old is already the mom of daughters Isabella and Francesca.

Cassandra is Caitlyn’s eldest daughter from her first marriage to Chrystie Crownover. However, the father-daughter duo didn’t always have a tight-knit bond. Caitlyn has said that she was often absent from the lives of her older children, including Cassandra and Burt, 38, from her marriage to Crownover, and Brandon, 35, and Brody, 33, from her second marriage to Linda Thompson.

“We have a very complex relationship,” Cassandra said during the talked-about family sit-down with Diane Sawyer in 2015. “He’s disappeared out of our lives, especially out of my life. So I’m looking forward to this next chapter."
