Pregnant Nadine Coyle is expecting a baby girl

Nadine Coyle is expecting a baby girl.

The former Girls Aloud star announced her pregnancy in August after reuniting with her ex-partner Jason Bell and the singer has now posted a photo on Twitter and Instagram of a duck-shaped balloon from her baby shower with "It's a girl" written on it revealing the tot's sex.

The 28-year-old pop star received dozens of well wishes from fans who assumed the star had given birth, but Nadine responded saying it was merely a baby shower balloon.

She tweeted: "Thank you for all your lovely messages. She is not born yet. That is a baby shower balloon. We can't wait until she is. Loads of love! Xx. (sic)"

Nadine also said 2013 had been her "best year so far".

The brunette beauty was shocked when she discovered she was pregnant and always thought one of the other Girls Aloud members - Sarah Harding, Kimberly Walsh, Cheryl Cole and Nicola Roberts - would have a baby before her.

She previously said: "I think I was the least likely to be the first to have a baby ... 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."
