The competition on "American Idol" just got a whole lot wider, with frontrunner Kenedi Anderson's shocking withdrawal from the competition. 

The show's longtime host Ryan Seacrest announced the news in a clip inserted into Monday's episode after the 17-year-old high schooler's performance of "Human" by Christina Perri, which brought judges Katy Perry, Lionel Richie and Luke Bryan to a standing ovation.

"You might have noticed that there was no voting information during Kenedi’s performance just now," Seacrest said while sitting at a table. "Since we taped these shows in Hawaii earlier, Kenedi has decided to withdraw from our show for personal reasons."

He added: "We send her well wishes, and needless to say, we have incredible talent on this historic season, with more iconic ‘Idol’ performances coming up for you right now."

Anderson has been a favorite to win since she auditioned with a soulful rendition of Lady Gaga's "Applause" that inspired the judges to award her one of three platinum tickets, sending her not only to Hollywood Week, but also past the first round of cuts.

"You might be the biggest star we've ever seen," Bryan told Anderson after her audition, which has garnered over 4.9 million views on YouTube. "I truly believe your musical journey for the rest of your life just started right here."

During Hollywood Week, Anderson followed up with more impressive performances, singing Bill Withers' "Lean on Me" with fellow contestant Jordan Chase for the duet round and Bruno Mars' "Talking to the Moon" for the showstoppers round.

On Monday, Anderson sang at Aulani, a Disney resort and spa in Hawaii, to a live audience as part of a lineup of 12 contestants from the top 24.
