The 28-year-old posted a photo of herself on her Instagram account, with the caption: "I am having a baby."
The Northern Irish star will become the first Girls Aloud singer to become a mother.
The band - with Cheryl Cole, Kimberley Walsh, Sarah Harding and Nicola Roberts - recently reunited for a 10-year celebration tour but split after their final concert in March.
Coyle suggested she wanted to continue, tweeting her fans: "You should know by now I had no part in any of this split business. I couldn't stop them. I had the best time and want to keep going."
She released her last solo album, Insatiable, in 2010, but it peaked at only number 47 in the UK charts.
Coyle, who recently said that she was working on new solo music, split from her ex-American footballer fiancé Jason Bell in 2011 but he was pictured watching the group perform in London earlier this year.
