The former American Idol winner, 27, made the big announcement during a charity concert Sunday in Jacksonville, Fla.
“You are the first [people] that I share this news with,” she told the audience gathered at the opening of the Riverview Apartments complex.
“And I share this with you because I can relate to you. And for a while, I walked around figuring out what they will say and what will they think about me. But now I tell you, I don’t live my life for folk.”
Revealing her joyous news, she added: “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.”
Barrino – already mother to a daughter Zion, 9 – made no mention of the impending baby’s father.
The singer has most recently been romantically linked to Antwaun Cook. Their relationship made headlines last summer after his divorce from Paula Cook was linked to his affair with Barrino.
She previously said that the negative attention she received for the relationship was one of the reasons she was driven to attempt suicide in August 2010.
