Good Morning America’s Ginger Zee has welcomed her second baby boy with husband Ben Aaron.

Zee and Aaron used social media to announce the birth of their son Miles Macklin. The bundle of joy was born on Friday, February 9th in New York City. He weighed in at 8 pounds 7 ounces and was 21.5 inches long.

Baby Miles joins big brother, 2-year-old Adrian, who helped his mom share the news of his little brother’s birth on social media. Dressed in scrubs with Big Brother embroidered on them, Zee made the announcement. Soon after, she shared a photo of her two sons together with Adrian hugging Miles.

Last August, Zee revealed on air that she and her media personality husband of four years were expanding their family. She used a very special weather map to prepare viewers for what was coming and express her excitement over the news.

The busy mom kept going right up until giving birth to her new son. Fourteen hours before her scheduled delivery, Zee walked the runway at the American Heart Association's Go Red for Women Red Dress Collection event. She looked radiant in her red dress, as she smiled the entire time she was on the runway.

Throughout her second pregnancy, Zee talked about how she and Aaron were preparing their oldest child for the baby. They gave him his own private tour of the baby’s room. He received a special big brother T-shirt that matches a little-brother onesie, which will now be worn by baby Miles. She also revealed they spent a lot of time reading books and watching TV shows about what it is like to be a big brother with Adrian.

Ginger Zee and husband Ben Aaron have expanded their family. They are now officially a family of four with son Adrian and new baby Miles. The famous weather lady will be off air for a while, as she bonds with her new son and adjusts to life with two little ones. Her GMA family gave her a fabulous send off last week, which included a special guest and a number of presents.

Congrats to Ginger, Ben, and Adrian on the new addition to your family! Welcome, baby Miles!
