The world's about to get a bit more Alouder: The first Girls Aloud baby is on its way!

Nadine Coyle hasn't had much to say since the British all-female group split in March, but she certainly knows how to grab the spotlight! The 28-year-old Irish singer posted the happy news on her Instagram today (Aug. 15), with the caption "I am having a baby. Xx."

Coyle has not announced when the baby is due or who the father is. Rumors suggest the baby daddy could be her on-again, off-again sweetie, Jason Bell. Her engagement to the ex-NFL player ended in June 2011, but they were spotted together earlier this year.

When Girls Aloud broke up following their 10th anniversary tour, Coyle was the sole holdout, taking to Twitter to tell fans she disagreed with the decision: "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 & want to keep going. Xxxx."

Looks like she found a pretty good way to keep herself busy, though!
