"Dave and I welcomed a healthy, happy baby boy at 9:47 p.m. Friday, Nov. 29," Burnett told People magazine. "He weighed in at 8 pounds, 10 ounces."
The 37-year-old host of CNN's "OutFront" married David Rubulotta, a managing director at Citigroup, in December. The couple announced the pregnancy in June.
"Seeing him for the first time was the most awe-inspiring, joyful moment of our lives," Burnett said.
The baby's name wasn't reported.
