Brandon and Leah Jenner are ecstatic over the arrival of their first child, according to Hollywood Life.

Leah Jenner announced the arrival of her and Brandon's little bundle of joy as well as her name via Instagram.

"On Wednesday, July 22nd I became a Mom," Leah Jenner captioned a photo of her taken when she was still pregnant. "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."

According to Daily Mail, Leah's family and close friends threw her a baby shower a few days before she gave birth.

"The extravagant affair featured a mix of blue and pink decorations, incuding baby clothing, beautiful rose bouquets, and hanging lights," Daily Mail reported.

"The intimate soiree was also designed to feature white chairs and matching table linens, as well as lawn umbrellas."

Brandon's mother and Caitlyn Jenner's ex-wife, Linda Thompson Instagrammed about the event and how excited she is in meeting her new grandchild.

"Imagine my joy & gratitude that @brandontjenner & @leah_jenner are blessing our family with a baby soon. Leah's mom & I are throwing this delightful baby shower for them at their home," Linda Thompson captioned her post.

Amid the Jenner clan's celebrations for the arrival of Brandon and Leah's child, there's one question on fans' minds: will Baby Eva James be calling Caitlyn Jenner grandpa or grandma?

It has been earlier reported that Caitlyn Jenner would still want to be called dad by his children despite her gender transition. After all, they've known her when she was still a man and changing how they call her could be confusing, at least at first.

However, Caitlyn Jenner is already a woman when Baby Eva James was born, which could change how the former Olympian would like to be addressed by her grandchild.
