Robbie Williams and Ayda Field's daughter Theodora made her first public appearance at Princess Eugenie and Jack Jack Brooksbank's wedding on Friday.
And the uber-cute six-year-old showed she was very much her father's daughter with her cheeky questioning of the mother of the bride, the Duchess of York.
Teddy - as she is affectionately called by dad Robbie and mum Ayda Field - totally stole the show as the eight-strong procession of flower-girls and page boys left St George's Chapel after the royal nuptials.
Striding confidently down the steps and calling out to Sarah Ferguson, little Teddy was caught on video demanding to know just who the Duchess of York was.
"Are you the Queen?" Theodora asked.
No, I'm not the Queen

An obviously bemused Sarah, who was making her way back to her car, stopped and replied: "No, I'm not the Queen."
This wasn't enough to satisfy the curiosity of Miss Williams though, who pressed on with her interrogation.
"You're a princess?" the little girl asked.
Sarah settled on a light-hearted "Yes", before dashing off to her vehicle.
Obviously happy with this answer, Teddy turned her attention back to the job in hand - waving enthusiastically and lapping up the adoration of the cheering crowds.
How adorable is she?!
Fans were amused by the moment, with one person writing on Twitter: "Love this, too cute!"
Love this, so cute xx

According to the Daily Mail, Teddy was chosen to accompany Eugenie down the aisle because of Sarah's friendship with Ayda and Robbie, which reportedly began when they holidayed together in 2011 on a yacht owned by Phones 4U businessman John Caudewell.
The other pint-sized attendants were Prince George and Princess Charlotte, Eugenie's goddaughter Maud Windsor, Peter and Autumn Phillips' daughters Savannah and Isla, Princess Anne's grandaughter Mia Tindall, and Louis de Givenchy, the son of a friend of Eugenie and her new husband Jack.
Lady Louise Windsor, the 14-year-old daughter of the Earl and Countess of Wessex, had earlier in the day been tasked with herding the youngsters into the service.
The viewing ratings for the nuptials have since been announced.
The Windsor wedding peaked at 3.9 million when it aired on the channel in an extended This Morning special hosted by Eamonn Holmes and Ruth Langsford from 9.25am until 12.30pm, according to overnight ratings.
This was up by more than two million viewers compared to the time slot’s average for 2018 so far of 856,000.
