Northern Irish singer Nadine, 28, surprised fans by announcing this morning (15 August) that she is expecting her first child.
Nicola is the first member of Girls Aloud to send a public message of well wishes to LA-based Nadine, tweeting: "Congratulations on your lovely news x."
Coincidentally, Nadine announced her pregnancy news just as fellow band mate Cheryl Cole jetted into Los Angeles. We wonder if they'll be meeting for a catch-up?
Nadine announced her pregnancy via an Instagram picture of herself with the words, "I'm having a baby", scribbled across the top.
She has not announced who the father is.
Nadine was previously engaged to American footballer-turned-financial advisor Jason Bell. They began dating in 2008 but separated in 2011.
Prior to that she dated Desperate Housewives star Jesse Metcalfe.
