"Fell madly in love w Harper Estelle tonight. Thx for the kind words and well wishes," wrote Wolfe, who had been blogging about her pregnancy. "Other than that I'm speechless."  Accompanying the tweet was a close-up shot of the baby, swaddled in a blanket and wearing the signature pink-and-blue hospital cap.

On Thursday, Wolfe and Goske spoke with the Today show live from the hospital, revealing how they selected the child's name.

"It's the perfect combination of athleticism and gentleness and kindness and beauty and a little TV moxie," said Wolfe, who also revealed that her real last name is Wolfeld. "It's out of the bag," she joked.
