I want to know the answer to the following question:
Which American Idol contestant has won the biggest number of Grammy Awards?
All the background I'm provided with is that "Underwood has since sold 65 million records worldwide, and become the most successful Idol contestant in the U.S., selling over 14 million albums copies in the U.S. and has more  Underwood has won seven Grammy Awards, the most Grammys by an "American Idol" alumnus.". Is that enough to answer the question?
Answer: no
