Urban, the ever-smiling 20-year-old from Duncanville, Texas, failed to impress the judges or the voters with his pitchy rendition of "Better Days" by The Goo Goo Dolls on Monday night's inspirational episode.
Judge Simon Cowell called it "a little bit of a let down," while Ellen DeGeneres compared Urban to soup du jour, "sometimes I like it, sometimes I don't."
Urban was joined with Aaron Kelly and Casey James in one of the seasons few all-male bottom three.
Prior to learning Urban's fate, the viewers were showered with a sporadic list of scheduled celebrity appearances and musical performances.
President Obama and First Lady Michelle Obama opened up the show with a recorded speech about helping others. Bill and Melinda Gates later tagged on to this notion and encouraged viewers to donate whatever they could.
Among the celebrity appearances, Jennifer Garner, Ben Affleck, Jim Carrey and Victoria Beckham were the most notable. However, the night also included a random appearance from Octomom, the American woman who came to international attention when she gave birth to octuplets in Januaray 2009.
Queen Latifah was Ryan Seacrest's co-host and introduced all the musical acts that performed in the Pasadena Civic Auditorium.
The Black Eyed Peas performed their latest hit, "Rock That Body," Joss Stone sang a soulful ballad with English guitar icon Jeff Beck on "I'll Put a Spell on You" and Elton John ended the night with his chart topping favorite, "Your Song."
Wednesday night's show was the third edition of "Idol Gives Back," and at the end of the show Simon Cowell announced that $15 million had already been raised.
Next week's episode will have the remaining contestants performing music from the next mentor, Shania Twain.
