Halliwell gave birth on 14 May with her sister Natalie at her bedside

She told Hello! magazine the flowers had seemed to be everywhere she looked towards the end of her pregnancy.

Halliwell's mother had also informed her that the bluebell was growing rare, and as something "precious" it seemed appropriate as a baby's name, she said.

The 33-year-old chose Madonna because the girl was born screaming with "both arms flung wide in the air", reminding her of the singer of the same name.

She said it was "as though she was shouting, 'hello, Wembley!'"

"No-one else has that name, apart from the Virgin Madonna and the singer, whom I love," Halliwell added.

There is also a family connection, as Halliwell's grandmother was a member of a risque dance troupe in Paris called the Bluebell Girls.

She described being a mother as "like having my own little doll".
