(Undated)  --  Carrie Underwood is "American Idol's" most successful alum -- at least from a financial standpoint. 

The country star and season four winner on the Fox reality show is topping "Forbes" magazine's latest list of the Top-Earning "American Idols," with an income last year of $31 million.  The publication also points out that Underwood has raked in $83 million over the past five years. 

The inaugural "Idol" winner Kelly Clarkson is taking a rather distant second place on the list, with earnings of seven-million.  Scotty McCreery and Kellie Pickler also make the cut.
