‘I think we just forgot to tell everyone we were together’
The 28 year-old, who announced she was expecting in the summer, has confirmed that her ex-fiance Jason Bell is the father and they are back together.
Having kept his identity a secret until now, Nadine said that she and the former American football player ‘just forgot’ to tell fans they had resumed their relationship.
‘I think we just forgot to tell everyone we were together,’ she told a UK magazine.
She added: ‘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!’
The singer also confessed the news she was pregnant came as a shock, saying she thought she would be the last of her Girls Aloud bandmates to have a baby.
‘I think I was the least likely to be the first to have a baby, it would always come up,’ she said.
'It was definitely a shock'
‘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.’
35 year-old Jason said: ‘I've never felt excitement like this in my whole life. Knowing we're having a baby takes it to another level.’
Nadine and Jason, who is divorced from his first wife Kimberly, started dating in 2008 and announced their engagement in September 2010.
However, by June 2011, they had separated with Nadine insisting they were 'great friends'.
In March this year, Nadine and Jason sparked speculation they had reignited their romance when he flew to London to watch her perform with Girl Aloud on their farewell tour.
And despite recent reports of hostility among band memebers, Nadine said she hoped Girls Aloud would reunite.
She said: ‘I didn't want it to end - but the sequins, the wings and a bump wouldn't have been a good look. I loved the reunion and hopefully one day we will get back together to do something else.’
