ABC News Correspondent Mara Schiavocampo Welcomes a Boy, Cruz Achille Porter

— -- ABC News correspondent Mara Schiavocampo and her husband, Tommie Porter, welcomed their second child today, a healthy baby boy named Cruz Achille Porter.

"Achille was my grandfather's name," Schiavocampo, 35, explained.

She gave birth to their son at 5:33 a.m. in New York City. The baby, who was due on January 11, weighed in at 7 pounds, 11 ounces.

The baby “arrived lightning fast overnight,” the happy mom wrote, “10 minutes after we got to the hospital before we even completed our admission paperwork.”

He joins 4-year-old big sister, Nina.

In July, Schiavocampo announced her pregnancy on "Good Morning America" weeks after ABC News Chief Meteorologist Ginger Zee shared her baby news.

At the time Schiavocampo said her husband was rooting for a boy. She said she couldn't be happier for the new addition.

“We're calling the baby 'the sequel' for now," Schiavocampo said, adding that "becoming a mom is the best thing that ever happened to me ... I'm just so excited and thrilled and blessed."

Schiavocampo opened up about her struggle with her weight after the birth of her first child in 2011 in her book, "Thinspired: How I Lost 90 Pounds -- My Plan for Lasting Weight Loss and Self-Acceptance," which is now in paperback. By completely eliminating her personal binge-eating triggers, Schiavocampo was able to lose 90 pounds and adopt a healthy lifestyle, embracing exercise and clean eating habits.

"I'm craving hard candy like crazy,” she explained in July of her pregnancy sweet tooth, but "trying to stay away by eating fruit."
