"I'm so in love. I can't even handle it," the WWE Superstar wrote Tuesday alongside a photo of herself cradling Birdie while staring at the infant lovingly.

The "Total Divas" and "Total Bellas" star's twin sister Brie Bella and her husband Daniel Bryan, real name Bryan Danielson, welcomed Birdie earlier this month.

She arrived weighing in at 8 lbs., 10 oz., and measured 21 inches long.

Brie recently detailed the story behind the birth of her daughter in a new video posted onto the Bella Twins YouTube Page Monday.

"I tell you what when Bryan and I heard that first cry after 21 hours of labor, he and I both started bawling crying," she said of hearing Birdie for the time alongside Bryan.

Brie also shared a photo of Nikki visiting Birdie in her home on Instagram with the caption, "Look who's in town!!!! Auntie Coco!!!! @thenikkibella #bestauntever."

Nikki last made headlines in April when her boyfriend John Cena proposed to her in the middle of the ring at WrestleMania 33. "I forgot how to breathe," she said of the moment.
