Nadine Coyle has confirmed her ex-fiance Jason Bell is the father of her unborn child.

The Girls Aloud singer has revealed she has reconciled with the former American football player and admits she expected everyone to assume he was the dad, despite not saying who the baby's father was when she announced her pregnancy in August.

She said: ''I think we just forgot to tell everyone we were together.

''When I said I was pregnant I thought, 'Why's everyone wondering who it is?' Then I remembered, 'Oh yes, that's right. I do stuff on TV and people are confused.' So this clears it up!''

Jason - who dated Nadine from January 2008 until they split in March 2011 - added: ''I've never felt excitement like this in my whole life. Knowing we're having a baby takes it to another level.''

The 28-year-old beauty admits she was shocked to discover she was expecting and insists she has always been the ''least likely'' member of Girls Aloud - who also include Cheryl Cole, Sarah Harding, Nicola Roberts and Kimberley Walsh - to be the first to have a child.

She added to HELLO! magazine: ''I think I was the least likely to be the first to have a baby, it would always come up.

''A couple of the other girls had wanted babies for a long time but I said no way ... It was definitely a shock, but I was really, really happy.''
