Singing sensation Adele gave the middle finger Tuesday night at the Brit Awards when she was cut off by producers during her acceptance speech. Here are other celebrities who weren't afraid to speak their minds during their moments in the spotlight.
Singers Lily Allen and Elton John got into a verbal scuffle while co-hosting the GQ Men of the Year Awards in 2008. John accused the singer of drinking too much at the show, while Allen fired back several obscenities and stated, "I'm 40 years younger than you. I have my whole life ahead of me."
