After last week’s criticism of not being confident enough, Amber Holcomb proved the judges wrong during last night's 'American Idol' with an effortless performance of Whitney Houston's 'I Believe In You and Me.'

Even though Randy Jackson was hard on Amber last week, he was impressed with her improvement, claiming she’s “in it to win.”

Nicki Minaj called the singer's set "a ten billion, katrillion." Oh Nicki, we're assuming that's a good thing.
