A firing frenzy has overtaken Tyra Banks and America's Next Top Model, as three personalities who have been with the series since its 2003 inception will not have their contracts renewed.

The ousted include:

1. Judge/Photographer Nigel Barker.
2. Creative Director Jay Manuel.
3. Runway Trainer J. Alexander.

The series, currently airing its "British Invasion" themed 18th cycle, will undergo "major changes" heading into next season, an America's Next Top Model insider tells The New York Post, while Executive Produer Ken Mok says in a statement:

"Nigel Barker, Jay Manuel and J. Alexander have been an integral part of the 'America's Next Top Model' brand and they helped turn this show into the household name it is today. They have been amazing assets to the show and will always be a part of the 'Top Model' family. We will continue to actively work with each of them on future projects."
