The American Idol season 3 winner gave birth to a baby boy, Dallas Xavier Barrino, her rep tells PEOPLE. Baby Dallas made his debut on Tuesday in North Carolina at 7 lbs., 9 oz. and 21 inches long. He joins big sister Zion, 10.
"I feel so blessed that my son Dallas Xavier was born healthy, and is a wonderful new addition to our family," Barrino, 27, tells PEOPLE. "I thank all my fans for their well wishes and continued support."
The singer expressed her joy about the new baby when she revealed in August she was pregnant, telling the audience at a charity concert in Florida: "So, this child that I carry – God has given me this child. And I don't have to hide it from none of y'all."
In October, she announced she was having a boy, and shared that she'd been placed on bed rest as she came into the home stretch of the pregnancy.
Barrino has not spoken about the baby's father, but the singer has been romantically linked to Antwaun Cook since summer 2010.
