Thousands turned up at mass auditions for the first series, which created Hear'Say and Liberty X.
Big Brother twist
Popstars II: The Rivals is looking for two bands this time round - one girl and one boy band.
And there's a Big Brother style twist to the show this year.
The judges will pick 10 girls and 10 boys as finalists. They will live together, Big Brother-style, in two houses, next door to each other.
The public will then vote to evict a girl and a boy each week until the final line-up is left.
