American Idol is one of the United States biggest reality and talent shows. Believe it or not, it had been going for 14 seasons before FOX cancelled it just over a year ago.

Luckily for us ABC have announced they will be reviving the hit show for an incredible 15th season soon.

The show has found some incredible stars in its time; from the one and only country star Carrie Underwood, to more quirky contestants like Adam Lambert.

Some have gone on to sell multi-platinum records and have hugely successful music careers since the show. Others have taken a completely different direction from singing.

Whether they won the Idol crown or not, these contestants have come on leaps and bounds since their time on the show.
