The mother of Shane Warne's children - his ex-wife Simone Callahan - has warned Liz Hurley to stop trying to be a mummy to HER kids.

Simone Callahan was left 'hurt' after Liz told a mag that Brooke, 14, Jackson, 13, and Summer, nine, call her 'Mummy Two'.

Simone has said it is 'just disrespectful as far as I'm concerned' adding: "She is not their mum. And the kids know exactly what the situation is."

Shane's ex has also said she was not happy that the children were part of a Hello photo-shoot with Liz and Shane on a holiday in Sri Lanka. She said she had always tried to protect her children and keep them out of the spotlight:

"They're young and impressionable," she tells Australia's Woman's Day magazine, "And I've always tried to keep them grounded and ensure life for them is as normal as possible."

Simone also spilled the beans on a difficult visit Shane made with Liz to their daughter's Melbourne school:

"Shane and Liz turned up – along with a swag of photographers," Simone, 42, reveals, "but we didn't speak at the assembly."

Shane and Liz - who has one child of her own, 10-year-old Damian - have been an item for 18 months. The Mirror reports that the ex-Mrs Warne and 'Mummy Two' were introduced for the first time this month, with an onlooker describing the meeting as 'awkward':
"It was a little bit awkward at first. It looked like Simone enjoyed having Shane to herself when Liz popped away for a minute," the mole said.

The women had finally come face to face in Melbourne when they all went to watch Shane's son play Aussie rules football.

Simone said: "Liz started chatting and really was quite friendly. I was surprised how warm she was."

But you still don't want her playing 'mummy' to your kids, eh Simone?!

What do you think? IS Liz over-stepping the mark with her 'Mummy Two' moniker?
