'American Idol' fans upset about favorite contestant not making it to the finale

Sunday night's 'American Idol' was filled with amazing performances from the final four contestants. Chayce Beckham, Casey Bishop, Willie Spence and Grace Kinstler all put on a show with help from 8-time Grammy winner, and Billie Eilish's older brother, Finneas.

There were many great performances, like Casey's cover of Billie Eilish's "Wish You Were Gay," and Chayce's original song "23." But unfortunately, only three can move on to the finale. So after Ryan Seacrest told Chayce and Willie that they were moving on, the third spot went to Grace.

Fans were NOT happy that Casey fell short of the finale, but many found the silver lining that she could be the next Adam Lambert. Maybe Casey's biggest fan, Luke Bryan, who thought she could win the whole thing, gave her a shout-out on Twitter, writing, "Casey Bishop, you're a true rockstar. This is just the beginning for you. Walk out of here with your head very high." And with performances like her killer cover of Mötley Crüe’s "Live Wire," this 16-year-old rocker clearly has a bright future.
