Ellen DeGeneres doesn't need to even say a word to make people laugh -- just ask Beyonce! The talk-show host didn't make it easy for the singer to introduce Justin Timberlake at the Grammys. As the composed singer delivered her scripted praise for JT's comeback performance, Ellen slapped on an ear-to-ear grin and stared at Bey, from close proximity, and sent the audience into a giggle fit. Ever the professional, Beyonce held it together, but she did slowly ease away after she delivered her bit. Personal space, Ellen!
