The Harry Potter music backround switches perfect...

"She's a wizard Harry" 😂🔮

The Harry Potter background music is giving total feel

She's brilliant, absolutely adore her. Hope she goes far in the world and has a wonderful life performing magic.

Simon: So, your grandfather is a wizard? Izzie: Yes! *(What if she meant it.)*

legend has it that simon is still trying to lift that box

She's so well spoken.

People watching this like: - in bed - not in a full screen - reading comments

“So that means your grandpa,is a...Wizard?” “Yes”

"I thought that was Dumbledore" Man I was dying laughing🤣🤣

Sentence of the day from the judges “ how did she do that?”😂😆

Issy is truly a wonder, she is amazing and I support every minute of her magic journey!

" I thought that was Dumbledore " LOL

"I wanna impress Simon, because he is the boss" lol

she's better than the adults, she deserves the golden buzzer.

She is not just confident, and sure of herself; she is also of a genius IQ. All you have to do is look at her eyes and you can see a brightness and intelligence there that you won't see in your average 8 year old. She's incredible, and she will go very far in her life.

When she said "When i grow up i want to be Hermione harry potter, because shes a wizard.... i mean witch" That was just to cute

Person: You are serious- Issy: I'm not Sirius, I'm Hermione.

The box trick was pretty incredible and seeing Simon's reaction to it was hilarious.

Legend has it that Simon is STILL trying to lift the box 🤩

she’s so well spoken

When the Harry Potter soundtrack came on I died, nostalgia just punched me IN THE FACE!

Best AGT audition ever, cutest little girl ever!

This deserves a golden buzzer tho

Her pronunciation and her smile are so cute

Love this girl she loves hermine from Harry Potter

You are an outstanding magician, Issy. Thank you.

WHAT a huge Harry Potter fan,here!! She DESERVED that golden buzzer alright!!

The girl that’s 8 : does magic super well Me at 8: looks under my bed to see if there’s any monsters

She's so beautyful :)

Can’t believe it’s been 5 years since this act!! This was one of my favorite BGT acts!

So precious... Blessings to you and your family.

She's like a mini Hermione Granger she's absolutely adorable!!

I bet she's gonna be a great asset to the Gryffindor house

Awe, she is Perfect !

She’s cute, she’s did the trick very well, she made grown men looks like kids, she has a great feature coming up, her grandfather rocks for teaching her.

Sometimes I have to sit down and accept that some people are actual wizards and I was not lucky enough to be one of those people.

Who’s watching in this hard time of covid 19

This gave me goosebumps

She’s so amazing!!!

She’s a natural, her stage presence and magic act was perfect. I loved it... and could she be any more adorable?

her accent:like hermione her looks:like hermione plus she does magic plus she is bossy plus she loves books. She's basically hermione duhhhh

Her smile can win many hearts😍 too

Issy Is very awesome and she impressed me with her magic ✨👏👏

I bet simon's over here wondering where to get Izzy's shirt

This was SO good. The whole routine - smart articulate. Nothing superfluous- and very charming besides being magical. Well Done Izzy🤩

She’s magic 🎁🎉👏

I love Simon and David's look of confusion towards Issy when they couldn't lift the box!

Her at 8 years old: doing incredible magic Me at 8 years old: wondering if teachers live at school

how dare she preform such magic in the presence of *muggles*

I love the Harry Potter music in the background

Harry Potter is already 25 years honey , you are just Amazing!!!!

Me at 8 In The Britain's Got Talent Stage: *Whispers, 'pick the word KETTLE'* Her at 8 In The Britain's Got Talent Stage: *Does it without saying anything*

me : nobody can be bossier than simon cowell she : hold my box

Did anyone see Simon mouthing "HOW DID SHE DO THAT!" at 5:00

That little girl is so smart and she did a good job wow she like blew my mind love u little girl Lol !

adorable, she's really talented and not at all nervous, most kids that go on shows like that look like they might start crying at any moment, she kept her composure and impressed everybody even Simon Cowell.

Her confidence is so adorable o bet she owns every room she walks into. She is also so well spoken. I felt like most British people are, especially the children. It’s insane.

Her at 8 :Does Magic Me at 8 :Still wondering how is 1×0= 0

Plot twist *Issy is Harry Potters Sons Daughter* *harry potter is her grandfather*
