The 10-year-old is a huge fan of the sassy group, and can be seen posing shyly with her heroes Perrie Edwards, Jesy Nelson, Leigh-Anne Pinnock and Jade Thirlwall in a snap Katie uploaded to Instagram last night.
“Thanks SO much for making Princess night tonight at Ardingly,” Katie captioned backstage pic from their Summer Shout Out show, which was also attended by her estranged husband Kieran Hayler
Princess’ dad, Peter Andre, revealed last year that she’s obsessed with the girl band.
“It’s all about Little Mix, she’s asking me about Little Mix so I don’t know, does anybody know them? I’ll get them to say hello to her,” he told Bang Showbiz.
“It is weird as a parent when you hear your kids talk about other people that are in the music industry – Princess is constantly going on about Little Mix.”
It comes after mother-of-five Katie caused shock on Loose Women by revealing to the nation that she didn’t used to think her eldest daughter was beautiful.
“[Princess] was really was ugly. She really was. But she wasn’t to me. All the ugly ones in school turn out to be the swans,” the straight-talking star told the show on August 29.
Her backhanded compliment even extended to her most recent sprogs, Jet and Bunny from her current marriage to Kieran.
“Even Jet and Bunny were gorgeous to me but they’ve got to grow into themselves. Newborns always look like wrinkly old men,” she said.
Katie, 39, then came under fire for a second time just days later when she shared a video of Princess lip-syncing to the Jonas Blue song Mama – with long purple nails on display.
“Has she got tips on?” one eagle-eyed fan asked after the video was shared on Instagram.
“Too young for full hair and makeup imo,” another outraged fan wrote.
A third wrote: “Very good but she must be 6 or 7 and way to much makeup with weirdos out there.”
And another still typed: “She don’t need all that make up shes a living princess naturally ❤ if she isn’t the prettiest girl I’ve met i don’t know who is.”
