StreetDance is the world's first 3D dance movie - and it's out now!
In the film, a street dance crew is forced to work with ballet dancers in return for free rehearsal space. They realise they have to work together if they want to compete at the UK Dance Championships.
It stars some familiar faces - George Sampson, Diversity and Flawless all feature in the movie.
Sonali was lucky enough to be at the world premiere. Check out who she managed to grab for a quick chat on the red carpet...
Sonali chats to George Sampson
George plays a wannabe dancer called Eddie in the film. It's the Britain's Got Talent winner's first movie.
The teen started dancing at the age of six on the streets of his hometown Warrington in the north of England.
Find out how he got the part and what he thinks of ballet!
Aggro Santos and Kimberly Wyatt
The Candy duo with Sonali
London rapper Aggro Santos and former Pussycat Doll Kimberly Wyatt are on the StreetDance soundtrack.
They've teamed up on the incredibly catchy track Candy.
Aggro was born in Brazil and he started making music early - when he was two years old, his mum found him banging on a dustbin trying to play the drums!
Kimberly certainly knows a bit about dance - as well as her time in the Pussycat Dolls, she was a judge on reality show Got to Dance.
Lightbulb Thieves talk to Sonali
Meet Lightbulb Thieves - a new band that some people say could be Britain's answer to the Black Eyed Peas.
They're on the StreetDance soundtrack too. Their track Work It Out samples some well known ballet music!
Amazingly, the group's song was snapped up even though they haven't got a record deal - yet!
Sonali spoke to the foursome on the red carpet and, of course, she had to ask about that hairdo!
Sonali and dance supremo Arlene Phillips
You'll be hard pressed to find someone who knows more about dance than Arlene Phillips.
The choreographer has been working in dance for decades, doing everything from theatre to pop videos.
She was a judge on Strictly Come Dancing for the first six series.
Find out whether Arlene prefers ballet or street dance and see her show Sonali a move!
