The Loose Women panellist, 37, couldn't resist sharing a few snaps as they enjoyed a night watching The Vamps at London's O2.
In one, mum-of-five Katie is seen posing up a storm with her daughter Princess in the seat behind her.
And Princess Tiaamii, Katie's daughter with ex-husband Peter Andre, looks like SUCH a mini-me as she pouts into the camera alongside her famous mum.
One fan commented: "Love Princess' pose in the background, good photo of you xx."
Katie's third hubbie Kieran Hayler and son Junior were also in attendance at the gig.
All four posed for a family selfie during The Vamps concert, where the support acts included Conor Maynard, The Tide and Hometown.
In fact, Katie and co were lucky enough to meet the band backstage - and Princess and Junior look chuffed to bits!

Earlier in the day, Katie had announced she's selling something very close to her heart... Or at least they used to be!
The former glamour model revealed she is selling her breast implants for a whopping one million pounds.

She told her combined 3.04million Twitter and Instagram followers: "My Breast implants size 1050cc, £1,000,000.00 email firstname.lastname@example.org to buy, make an offer or for more info!"
However, many of her fans assumed it was an April Fool's joke.
After midnight, Katie insisted it was not a joke and also explained that the silicon could be used again as they have been sterilised.
She also added: "To buy implants your also get a meet great and can collect from my house xx."
