Do you fancy being first in line to watch princess of pop Britney's first film, Crossroads?
The film is about a girl and her mates driving across America on their way to a singing competition in LA, and we need one of you to review the movie.
If you win, you'll get to go to the premiere in London, and mingle with all the stars. Then you need to do a review for the Newsround TV programme, and one for the website too!
You've got to be free to come to London on 25 March, and don't worry, we'll pay for your travel, and accommodation if you have to stay over.
And you've got to answer this simple question:
What's the name of the character Britney plays in her movie?
You can apply in two ways:
1) You can either phone us with your answer on: 09001 114458.
Calls cost 30 pence maximum and the lines close on Wednesday at 9pm. Please get permission from whoever pays the bill.
2) Or fill out the form below and don't forget to include your answer!
We'll pick a winner and announce their name here at the end of the week.
