Myleene Klass still thinks of herself as a “single mum”

Myleene – who also has 17-month-old son Apollo with Simon – said: “I will always think of myself as a single mum.

“Absolutely. My girls are my responsibility and I don’t know any other way. Sim has come into the picture, we have a son and he says, ‘I have five children.’

“But my girls rely on me and I have to make sure I can guide them and look after them.”

But the former Hear’Say singer thinks Simon is an “incredible” dad and she loves the bond he has with Ava in particular.

She gushed to You magazine: “I fall in love with him every day, because he is such an incredible dad…

“[He and Ava] are very close. They plot against me if she wants a movie or pizza with her mates at 10pm or something. I like it and I let it happen because they have a unique relationship.

“That’s something that I didn’t think would ever happen and they are very protective of it.”

Myleene previously revealed she has had four miscarriages and while Simon would love for them to have another child, she’s unsure.

She said: “Sim would go tomorrow. But there’s a part of me that thinks, ‘Gosh, we’ve got our golden child here.’

“We have five children between us – it’s a lot. And I genuinely feel so grateful for where I am now.”

Apollo is named after the god of music and Science, but the toddler doesn’t acknowledge his real name because the entire household call him Snoopy.

Myleene admitted: “The children wanted us to call him Snoop Dogg.

“I said, ‘Don’t be ridiculous.’ Now nobody calls him Apollo. He doesn’t even answer to it. He only knows Snoopy.

“We nicknamed him the Emperor. If he learns to walk it will be a miracle because he only has to gesture and we bring him what he wants. We are all waiting on him hand and foot.”
