Harvey. 12, drew the picture to wish his mum good luck on the Channel 5 reality show and she has placed it next to her bed.
In the adorable sketch, Harvey - who suffers from a genetic disorder and range of disabilities including autism and sight problems - has given his mummy a very healthy glow.
Well, considering all the fake tan she's been applying while on CBB, we think it's pretty accurate!
Katie, 36, is also wearing a pink top in the drawing and has a very ample chest, which she was famed for before having her implants removed earlier this month.
Alongside the portrait, Harvey has written: "To Mummy, good luck, love Harvey." Cute!
We're not the only ones to have spotted the sketch, as Katie's brother Danny has also tweeted about it while manning his sister's account.
He said: "Ahhh lovely pic by Harvey on the wall wishing mummy good luck #cbb #cbbkatieprice."
Katie and son Harvey have found themselves in the headlines this week following a comment she made on CBB regarding his transport for school.
On Monday, Katie was seen telling outspoken Katie Hopkins that the government pay for a driver and a nurse to accompany her son to his special school in London.
Earlier today, Katie's mum Amy defended her daughter in an interview after the former glamour model received criticism for not paying the bill herself.
Amy explained that Harvey travels a 100-mile roundtrip daily after his local special school closed down (despite Katie campaigning to keep it open), adding: "It's so hurtful that people can criticise my daughter for doing the best she can for Harvey."
Since then, Danny has also thanked the public for their "overwhelming" support.
