The mother-of-two took to Twitter to reveal a comical misunderstanding involving her daughter Ava.
A letter was sent to the former Hear'Say singer, after her five-year-old daughter revealed at school that her mother locks her in a cupboard.
'My 5yr old has reported I lock her in a cupboard at night and turn off the lights'
Referring to her daughter's overactive imagination, the 35-year-old tweeted: ‘Received a letter from school: My 5yr old has reported I lock her in a cupboard at night and turn off the lights. facepalm.’
The Marks and Spencer model later added: ‘One for the scrap book. #mumoftheyear, going to lock myself in the cupboard and turn out the lights!’
Myleene recently made a special appearance at her daughter’s school, where she talked about music and even played the piano for the lucky youngsters.
‘Just played piano/gave a talk at Avas school. Probably most nerve wracking thing I've done. Rewards self with wotsits,’ she said on Twitter.
The ex pop star also addressed the possible Hear'Say reunion rumours, sparked after ITV’s The Big Reunion show reunited bands including 5ive, Atomic Kitten and Liberty X for a special tour.
She said: 'I don’t think any member of Hear’Say would do The Big Reunion, and I know that because I speak to all the members of the band.'
