(LOS ANGELES) -- Jacob Lusk got the boot on American Idol Thursday night, leaving just four contestants still in the contest.
He sang "A House Is Not a Home" for his farewell song and continued doing vocal runs after the song was over and as the credits rolled. Lauren Alaina was in the bottom two with Lusk, but she'll be back next week.
The top five opened the show with a group performance of The Turtles' classic hit "Happy Together." Lady Antebellum also returned to American Idol to debut their brand-new single," Just a Kiss," and judge Jennifer Lopez took the stage for a highly-produced performance of "On the Floor" with Pitbull. She also gave a sneak peek of her new video for "I'm into You."
Speaking of videos, Lady Gaga's video for "Judas" was scheduled to premiere on last night's American Idol, but it never aired. No doubt the reason why is because it leaked online earlier Thursday, prompting Gaga to officially release the video before the scheduled Idol premiere.
If you were disappointed in the video no-show Thursday night, however, there may be something even better in store for next week. After Thursday's show, host Ryan Seacrest tweeted, "I only have one word for our mentor on @AmericanIdol next week...Gaga." If true, that pretty much says it all.
On Thursday's show, Seacrest also announced some of the audition cities for American Idol's eleventh season. They'll be hitting St. Louis on June 28, Portland on July 2 and Charleston, South Carolina on July 22. More audition cities will be announced next week.
American Idol's top four return to perform for the nation's vote next Wednesday night at 8 p.m. ET on Fox.
