"Melanie spent a while deciding on the baby's name," a friend of the singer tells PEOPLE. "It was inspired by a number of things."
On Tuesday, Brown, who lives in Los Angeles, explained the name in a brief statement released through her London reps.
"Angel, as she was my little angel through my pregnancy," she said. "Iris, as it's my grandma's name, Murphy because he's the dad and Brown because I'm the mum!"
Angel Iris is the second child for the former Scary Spice. She has an 8-year-old daughter, Phoenix Chi, with her ex-husband, dancer Jimmy Gulzar.
In March, Murphy's new girlfriend, film producer Tracey Edmonds, told Chicago's Power 92 radio station of Murphy: "There'll be a paternity test and if it's his then he'll be responsible."
All of this mess needs to stop. They're grown ass people acting like children. Has the paternity test been taken yet? If so, how long does it take normally take because this whole situation is way beyond getting on my nerves. I pray that the baby is Eddie's because Scary Spice is rallying behind her words that he is indeed the father. But hell, I'm sure she knows who she's been sleeping with so...... Let's just hope that it doesn't come out that Eddie had a vesectomy (sp) in his earlier years. LOL, Lawd that would be something!
