"&lt;strong&gt;Hayden Panettiere&lt;/strong&gt; turned 21 last weekend ... and she shared the whole experience with her fellow \"&lt;strong&gt;Scream 4&lt;/strong&gt;\" castmates -- plus a bunch of fire breathers, burlesque dancers and oompa loompas.&lt;br /&gt;&lt;br /&gt;&lt;a target=\"_blank\" href=\"http://www.tmz.com/photos/2010/08/23/2959-haydens-birthday-party\"&gt;&lt;img alt=\"0823-hayden-photo-launch-2-credit\" src=\"http://ll-media.tmz.com/2012/08/07/0823-hayden-photo-launch-2-credit-1.jpg\" /&gt;&lt;/a&gt;&lt;br /&gt;It all went down near the \"Scream 4\" set in Ann Arbor, MI -- according to our sources, &lt;strong&gt;David Arquette &lt;/strong&gt;helped organize the blowout party at some huge 4-story venue ... then filled it with crazy performers from &lt;strong&gt;Beacher's Madhouse&lt;/strong&gt;.&lt;br /&gt;&lt;br /&gt;&lt;a target=\"_blank\" href=\"http://www.tmz.com/2010/08/05/david-arquette-beachers-madhouse-jeff-beacher-hollywood-roosevelt-hotel/3/\"&gt;&lt;strong&gt;As we previously reported&lt;/strong&gt;&lt;/a&gt;, Arquette -- who also stars in the next \"Scream\" installment -- recently inked a lucrative deal with BM creator &lt;strong&gt;Jeff Beacher&lt;/strong&gt; ... all in the hopes of bringing the Vegas mega-show to Hollywood.&lt;br /&gt;&lt;br /&gt;As for that random dolphin -- it's actually a CAKE -- specifically designed because &lt;a target=\"_blank\" href=\"http://www.tmz.com/2007/11/01/cheerleader-in-dolphin-crusade/\"&gt;&lt;strong&gt;Hayden loves the little guys&lt;/strong&gt;&lt;/a&gt;.&lt;br /&gt;&lt;br /&gt;As for Hayden's BF Wladimir Klitschko -- he missed the party, but for a good reason. Dude is locked down at his training camp for his upcoming fight against &lt;strong&gt;Samuel Peter&lt;/strong&gt; in Germany. &lt;br /&gt;&lt;br /&gt;&lt;!-- relatedlinks --&gt;"^^<http://www.w3.org/2001/XMLSchema#string>
