Don't mess with Jenny from the Block! Jennifer Lopez was instrumental in saving Adele's Grammy acceptance speech at the awards ceremony over the weekend. Just before Adele began her acceptance speech, Ukranian television personality and prankster, Vitalii Seduik rushed onto the stage. Lopez then shot Seduik a dirty look and actually shooed him away. Seduik exited the stage and Adele didn't even seem to notice.
