Myleene Klass was confronted in the playground by angry mums after she criticised parents who asked for £10 contributions to buy a Kindle and a desk for their daughters' birthdays.
According to the Ham and High newspaper, the former I'm A Celebrity... star was picking up seven-year-old daughter Ava from her private school in north London when another mum called across the playground: "Why did you do it, Myleene? Why?"
The newspaper said Myleene shouted back: "If you've got a problem with it, talk to me in private."
Other furious parents have written and emailed the headteacher of the £5,000-a-term school accusing the star of using the personal emails of fellow parents to get press attention.
One wrote: "It was a very distasteful and cheap shot."
The confrontation happened after mum-of-two Myleene shared a group email she received from a mother of a girl who goes to private school with her seven-year-old daughter Ava.
Sent by one parent on behalf of two other mothers, it requested £10 donations from each classmate to go towards buying a Kindle e-reader for one pupil and a desk for another.
Myleene, who is also mum to three-year-old Hero, posted a picture of the message (after changing all names), which stated:
Her message went viral, being shared hundreds of times, and was also posted on national websites attracting thousands of views.
One furious mother, told the Ham and High: "She has betrayed our confidences and belittled us so publicly. Lots of people have complained."
Another said: "She has really p****d everyone off. It is so out of order. She isn't going to have any friends left and we are the ones she relies on to pick up her daughter for her when she is late."
In an email to other parents in the class, one angry mother wrote: "Next time she parks on the double yellow lines opposite school, I shall really try hard not to take pictures and sell it to the press!"
Another parent defended the class communal gift arrangement saying: "It is to make it easier for parents so they don't buy expensive presents that nobody wants.
"There is no obligation. Myleene has misunderstood the school's community spirit."
Another added: "It is bang out of order. 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. The press have certainly all been back here today."
Was Myleene right to point out grabbiness or should she have kept quiet?
