A COLIN the Caterpillar cake is as posh as most people's birthdays get.
But Pixie Curtis' multi-millionaire lifestyle was clear to see in her 12th birthday cake - with mum Roxy Jacenko sharing her daughter's delighted reaction on her Instagram .
As she sat down to look at the cake, she was instructed to pull the gold birthday sign on the top.
And, as she did so, she pulled a seemingly endless string of bank notes out of the middle of the cake.
Pixie failed to hide her delight as she watched the cash multiply before her very eyes, and held the complete string of notes up victoriously at the end.
Roxy had also decked out the room for her daughter's big day - with balloons absolutely everywhere.
She'd even splurged on a flower bouquet made entirely from balloons, but admitted "Okay so maybe I bought these for me! How fun."
In posts on e, she showed a table completely covered in presents for her daughter, alongside the stacks of balloons.
On the table were bags from designer names including Alexander McQueen, Tiffany & Co., Dior and Goyard.
"I love you @pixiecurtis," Roxy wrote alongside pictures of Pixie opening her presents.

"Happy 12th Birthday.
"Forever my best friend."
"Happy birthday beautiful pixie," one person commented on the post.
"Hope you got very spoilt - I know you did!
"Lucky girl, enjoy xxxxxx."
"When I grow up I want a table of presents like that ! ( I’m 59)," another laughed.
As a third commented: "Those gifts on the table are epic. Happy Birthday Pixie."
Of course, in true multi-millionaire style, Pixie had already celebrated her 12th birthday with her friends in style before her big day actually arrived.
The event doubled as a farewell for Pixie, who is moving to Singapore with her family in the coming weeks.
The party aptly had a Singaporean theme and guests were asked to wear white or red - the flag colours of the southeast Asian country.
Pixie stayed in a £1000-a-night suite at Crown Towers hotel in Sydney and treated her girlfriends to rooms so they could have a “staycation” together.
The beds were lined with gifts for each girl from teen health brand Allkinds, Aussie beauty brands MCoBeauty, Mecca Max and Naked Sundays, and artisan donuts from Dr Dough Donuts.
Posh florist Poho Flowers also provided bouquets for the rooms.
Pixie hired out a space at Italian restaurant Matteo, where a dish can cost up to £93, and Roxy enlisted party planners to provide over-the-top decorations.
There were even gymnasts providing entertainment with their performances, as well as Pixie's name emblazoned in signage around the room and on the floor.
