A four-year-old Scots boy doodled on his sleeping sister but told his mum 'the blue lines just appeared'.
Mischievous Enrico Graham was put to bed with his big sister Eva at around 7.30pm last night and mum Tasha Allan allowed the pair to watch some TV before the went to sleep.
But when the Cumnock mum-of-three went back up stairs a few hours later to check on them, she found her middle child sleeping soundly with her face covered in blue scribbles.
Knowing it was the handiwork of the her cheeky youngest child, she asked him if he was the culprit, but he denied knowing anything about it.
Tasha, 28, who is also mum to Ellie,11, said: "I let them watch TV for an hour before they go to sleep so I put it on and left them to fall asleep.
"A wee while later I went up to check they were ok and tuck them in and as I was getting to the bedroom Enrico shouted 'I'm hungry can you get me something to eat?'
"I went downstairs and got him a wee biscuit and took it back up and as soon as I went into the room i could see blue pen all over Eva's face.
"I said 'did you draw on your sister?' and he said 'No those blue lines just appeared'.
"I didn't want to wake her up and disturb her so I just left her until the morning. She woke up and couldn't believe her face was all blue."
Despite his denials, Tasha, said it's not the first time the youngster has taken to using his family members as a canvas.
She said: 'He did it before to his other sister but with red lipstick and it stained her skin so even when we washed it off, you could still see it. He's some boy."
Tasha shared the picture of unsuspecting Eva on social media and her friends and family saw the funny side.
She said: 'People thought it was funny and were commenting on it. He is a funny wee boy."
