The 30-year-old told hosts Holly and Reggie about his close friendship with singer Amy, who passed away last year.
"We were friends from about the age of 12 or 13," he explained. "We were like two peas in a pod, two halves of the same person."
Recalling learning about Amy's death last summer, Tyler described it as the "worst day of his life"
Performing Otis Reading hit Sitting On The Dock Of The Bay for the judges, Will.i.am was the first and only coach to turn around.
He remarked: “I want to say thanks for hitting that high note at the end, throughout your performance you sounded really great.
"That last note showed your range and how sooth you can. You’re awesome"
