Carson Daly and his fiancée Siri Pinter officially welcomed a new addition to their family on Wednesday.

The doting parents gave birth to a healthy baby girl who they named London Rose Daly, according to Yarmouth.

The "Today's" official Twitter account confirmed the news via the social networking site and wrote, "Welcome to the world, London Rose Daly! Congrats @CarsonDaly & @siriouslydelish! #CongratsCarson."

A photo of Daly cradling his daughter in his arms was posted along with the congratulatory message.

Pinter replied to the tweet and said, "Thanks for all the love!"

Daly and Pinter's adorable baby weighed in at 8 pounds and 11 ounces and measured 22 inches long, USA Today's Entertain This reported.

Following his daughter's birth, Daly expressed his gratitude and love for the mother of his child, the same publication noted.

"Siri is a warrior and I'm so amazed by her poise, grace and strength during this miraculous process," he said.

On Thursday, Daly also shared some exciting details on the morning show, the NY Daily News revealed.

"Baby and Siri are right here. They're doing very well. It's incredible. We thought this was going to happen on Saturday and it didn't. We went home, it was a long couple of days of waiting. Like out of a movie, I sped to the hospital and they were literally waiting for me to get there and we had our beautiful baby girl," he said.

When asked what inspired them to pick London Rose as the name of their baby, Daly explained, "We tried to pick something that matched our kids' names. Rose was my grandmother's name, Etta was Siri's grandmother's name... When London came out we were still throwing out names."

Meanwhile, this is the second birth among the members of the "Today" family. Just last week, Savannah Guthrie welcomed her daughter Vale Guthrie Feldman, TV Guide noted.

On Thursday, Guthrie also welcomed Daly's daughter via Twitter and wrote, "We are so glad you're here London Rose!! Much love to @CarsonDaly @siriouslydelish - Vale can't wait to play! #girls."

London Rose is officially Daly and Pinter's third child together. She joins older brother Jack, 5, and sister Etta, 2.
