Pop star Nadine Coyle is expecting a baby.
The former Girls Aloud singer, 28, shared the happy news with fans by posting a snap of herself on Instagram.com, alongside the caption, "I am having a baby".
The singer will be the first member of the Biology hitmakers to become a mother.
Coyle has not gone public with the name of the father, but she was last linked to U.S. businessman Waz Ashayer in 2012.
Girls Aloud split in March after completing a 10 year anniversary tour.
