The ride-on toy is an exact replica of the £100,000 convertible Katie bought herself in May while weathering the storm of the revelation of her husband Kieran Hayler's affair with her best friend Jane Pountney.
Katie posted a photo of Jett's extravagant new toy on charity photo sharing website YouGossip on Boxing Day, after previously revealing that she wasn't buying any Christmas presents for her youngest child, four-month-old Bunny, because she's 'too young to understand'.
"Bunny won't be getting any presents. They don't know at that age anyhow," Katie told OK! magazine.
"Princess and Junior have outgrown toys and they're into iPads and expensive items.
"I used to go mad and it got to a point where the kids would be bored of opening them as they'd still be opening them days later, so I'm not going to do that this year, it's a waste."
However, a photo Katie shared on December 23 showing her car filled with mountains of gifts to be wrapped, suggests that despite her frugal intentions she couldn't resist a Christmas spending spree.
Katie and Kieran spent Boxing Day at Katie's mum's house, with their two children Jett and Bunny, as well as Katie's older children, Harvey 12, from a previous relation ship with Dwight York, and Junior and Princess from her previous marriage to Peter Andre.
Katie took plenty of festive family snaps to mark the occasion.
