Former Facts of Life
star Kim Fields has welcomed a son, Sebastian Alexander Morgan, her rep confirms to PEOPLE exclusively.
The boy, who will be called "Sam," was born Friday at 11:30 a.m. (Fields was in labor for less than two hours.)
He weighed 6 lbs., 4 oz. and was 19" long. Fields – whose pregnancy and delivery were "trouble free, sickness free, very smooth, perfect," according to her rep – said upon first seeing her son, "Oh, my God. He's gorgeous."
This is the first child for Fields and her boyfriend, Broadway actor Christopher Morgan – who was in the delivery room, speechless and crying when his son arrived, said the rep.
Fields, 37, and Morgan, 30, who are engaged, have been together "a couple of years" and decided last summer to have a child, she told PEOPLE
"We were on the subway one day and Chris said, 'I'm ready to start our family,' " Fields recalled. "It was beautiful and I started to weep."
Had the new arrival been a girl, her name would have been Aria Grace, Fields said.
Fields played Tootie Ramsey on TV's The Facts of Life
throughout its run from 1979 to 1988. She also recently produced and directed a documentary about Grammy-nominated jazz saxophonist Najee called Najee: Sax in South Africa.Reporting by JULIE DAM
