Louise Redknapp has reportedly been "knocked sideways" after finding out her ex-husband Jamie is set to have a baby with his new partner.
Jamie's partner Frida Andersson, 37, is pregnant with their first baby together.
Model Frida has four children already, while Jamie has two with Louise.
Louise is said to have found out about the pregnancy news through family and that Jamie didn't tell her the news directly.
Harry and Sandra were apparently told about their new grandchild on the way before it hit headlines this week - reports Mirror Online.
Louise and Jamie have been co-parenting their sons Charley and Beau who have been dividing their time between their parents' homes.
A source told OK! magazine : "Louise was knocked sideways by the news. Jamie didn't tell her directly, she found out through family.
"She's happy for them both and says life goes on but at the same time, she's shocked by how quickly he's moved on and that he'll be a new dad again at nearly 50.
"A new baby is always a joy but she is concerned at how it will impact their family dynamic."
At their peak Jamie and Louise were a golden celebrity couple in the UK circles.
It sent shockwaves through the showbiz circuit when they called time on their marriage after 19 years.
They ended their marriage just months after Louise completed her Strictly Come Dancing stint.
Strictly gave her a new lease of life and spurred her on to chase her dreams of creating a life for herself in the spotlight.
Louise had hopes of carving out a high-flying career in the West End and reviving her musical career with touring.
But recently, Louise said she considered stepping out in front of a bus for a "split second" after her marriage failed.
However she found inner strength from the thought of her boys.
In an extract from her book You've Got This published in You magazine, she wrote: “I would be standing in central London, watching the buses whizz past and I would wonder whether it would be easier for a bus to take me out.
“All it would take was for me to step out at the wrong moment and it would all be over.
“I think so, for a split second. I was like, ‘I would really like this all to go away.’”
