But it wasn’t long until she had some exciting news to share, with a sweet photo of her baby’s tiny hand clutching one of her fingers.

The caption was just the date of birth - August 1 - with a single blue heart, with no announcement about a name or gender, but Klass had previously said that she was expecting her first boy.

Her new baby is her first with boyfriend Simon Motson, a fashion PR boss who already has two children from his previous marriage.

TV star and former popstar Klass already has two children, daughters Ava, 11, and Hero, seven, from her relationship with ex-husband Graham Quinn.

Klass’s final pregnancy post shared on Instagram was a nude side shot of her bump, which she captioned: "Will never get over or take for granted the miracle of growing and carrying a child.

"Mamas, you are all so incredible. Our bodies are incredible!"

She had already announced that she was expecting a boy when she shared a photo from her baby shower, surrounded by Motson, her daughters, blue balloons and flowers, and a banner that said “baby boy”.

It was back in February that she first told the public she was expecting baby number three, with a social media post on Valentines Day of herself cradling her bump.

Celebrity pals including Keith Lemon, Kate Thornton, Vicky Pattison, Alex Jones and Amanda Holden all offered their congratulations on Klass’s Instagram post of her new baby.
