Former Girls Aloud singer Nadine Coyle has announced that she is expecting her first child.

The star revealed the news on Instagram by posting a picture of herself looking surprised with the caption: "I am having a baby. X"

The 28-year-old from Londonderry does not mention who the father is or when she is expecting.

Earlier this year she was pictured with former fiance and American footballer Jason Bell.

The pair dated for three years but announced their one-year engagement had ended in June 2011.

She will be the first Girls Aloud star to have a baby after the band found fame on reality TV show Popstars: The Rivals in 2002.

Former bandmate Cheryl Cole tweeted her congratulations, writing: "I just woke up to the news that there is to be a baby aloud!! This is so crazy. But Amazing!!

"Congratulations @nadinecoylenow. Can't believe you're going to be a mummy!!!!!!!!!!!"

Ex-Girls Aloud star Nicola Roberts tweeted: "Congratulations on your lovely news x."

Nadine Coyle revealed plans this year to release new solo music.

Her debut album Insatiable was sold exclusively by Tesco in November 2010.

The album went to number 20 in the Irish Album Chart and number 47 in the UK Album Chart.

She was named Ireland's richest young star in 2012 with nearly £5 million in her bank account.

The Sunday Times young rich list also ranked her the 14th wealthiest singer under the age of 30 across the UK and Ireland.

Girls Aloud announced they were splitting up earlier this year following the last night of their 10th anniversary celebration tour.

The girl group had four UK number one singles, two UK number one albums and received nominations for five Brit Awards, winning best single in 2009 for The Promise.
