Giving viewers an emotional moment, a choked up Ryan prepared himself to say goodbye to viewers for the last time after 15 seasons on the show, but just as he spoke his famous phrase and the stage went dark, we heard two more words from the host that caused a stir with anyone who heard it.

"And one more time — this is so tough — we say to you from Hollywood, goodnight America," he said, before adding, "For now," to the bewilderment of everyone watching since this was supposedly the last and final season.

Seacrest later took to Twitter and tweeted his farewell to the show: ‘I didn’t want to say goodbye last night. Thank you for 15 amazing seasons #IdolFinale.’ he wrote. Show creator Simon Fuller recently told a magazine, however, that there’s definitely something on the horizon.

"There will no doubt be another format or refinement or elevation of the format. Now I can actually revamp it and come up with a new version. And we can look back on 15 seasons and think of some legitimate ways to allow people to enjoy them again, maybe adding another dimension to it," he said.
