Stars from around the world will be performing at the awards on Thursday night, while everyone waits to find out who's won the top prizes.
Ms Dynamite is tipped for the biggest success, as she could easily win any of the four categories she's nominated in.
'I never win anything'
The garage star is up for British female solo artist, British album, British urban act and British breakthrough artist.
Coldplay and The Streets are also expected to do well.
Pink, who's up for three awards, will be opening the show.
She told The Mirror: "I don't think I'm going to win, I never win anything."
Pop Idols Gareth Gates and Will Young are both up for awards, but won't be performing on the night.
The Brits are on ITV1 at 8pm on Thursday night.
