The 36-year-old excitedly shared the news that sales of her range with Littlewoods have increased by 200 per cent, after she slammed school mothers who asked for money towards their children's birthday presents.
Sharing a snap of her posing in a set of her underwear, Myleene said: "O.M.G!!!!! Girls!!! Sales of my lingerie are up by 200%!!!
"Please get in quick to ensure you get your order. Xx #littlewoodslovesmyleene @littlewoodsonline"
After the former Hear'Say singer mocked the mothers by sharing their emails online, she was blasted by them for 'looking for attention'.
One parent said: "It is bang out of oder. These are old class emails from a year ago.
"We have all noticed that the paparazzi are no longer outside the school taking her picture like they used to be every morning.
"Perhaps she needed to get some attention. They have certainly all been back her today."
The head teacher of the £5,000-a-term North London school, which Myleene's daughter Ava attends, even got involved in the row.
Taking a swipe at the Classic FM presenter via the newsletter, she said: "No more parking on zig zags. No more blocking in the neighbours. No more unicorns. And as my granny would've said, if can't tweet anything nice, don't tweet anything at all."
