Musicians Brandon and Leah Jenner welcomed their first child on July 22, a daughter the couple named Eva James.

Leah, who is one half of the Indie pop duo, announced the news on her Instagram on Sunday:

“On Wednesday, July 22nd I became a Mom. It has without a doubt been the most profoundly beautiful time in my life but also emotionally, spiritually and physically challenging too….and I am so grateful for every second of it. Brandon and I are taking care of our healthy, little baby girl, Eva James Jenner,” she wrote.

The new addition will have as playmates, the children of their dad’s half siblings: Reign, Mason and Penelope, children of  Kourtney Kardashian,  and North West and her soon-to-be born baby brother, kids of Kim Kardashian.

Eva’s other cousins’ grandad was Bruce Jenner who has since become Caitlyn Jenner so…this means Eva James is the first to have three grandmoms (???) Brandon’s mom Linda Thompson and Leahs’ mom Susan Felder and Caitlyn Jenner.

Congrats to the growing family!
