After a long week of excitement about "American Idol," "Iron Man 2" and a couple of bomb scares, the weekend has finally arrived. The world is your oyster this weekend, as you can catch a great comic book movie, watch the Los Angeles Lakers further dismantle the Utah Jazz in the NBA playoffs, check out Betty White and Jay-Z on "Saturday Night Live" and watch Mauricio "Shogun" Rua pummel Lyoto "The Dragon" Machida for the UFC Light Heavyweight Championship. And yeah, you should probably call your mother, too. But before you do any of that, be sure to check out all the stories you might have missed on the MTV Newsroom Blog this week.
