"Oh, my sweet little Birdie… From the moment I first saw you I knew it was unconditional love. I promise to protect and love you forever and ever.," she captioned the Instagram photo, which also showed off her 3-carat diamond ring from fiancé John Cena. The couple famously got engaged at WrestleMania 33 last month.

She also congratulated Brie and her husband Daniel Bryan (real name: Bryan Danielson) on their tiny bundle of joy.

"And my Brizee, you are the strongest, bravest person I know," she continued. "So happy God made us twins. Don't know this world without you. And wouldn't ever want to. Goodness, I love you both so much. PS Bryan never left her side, still hasn't, seeing him as a dad is amazing. He's so strong."

"The greatest feeling in the world!!! Can't even express the love I feel for her," she wrote. "From the moment I saw her I was in love. Thank you all for your love and support. Birdie Joe is her Daddy's mini-me!"

Now, Nikki is focused on her upcoming wedding to her own WWE superstar —including picking out the perfect wedding dress.
