"  Photo: Getty Images Last night, festival goers who stuck out the sand-filled winds and chilly temps in Coachella Valley were rewarded with a few glorious surprises. During Solange Knowles&amp;#039; set, Beyonc\u00E9 joined her sister onstage for an impromptu choreographed dance party. The performance gave us a glimpse of what it must have looked like growing up in the Knowles house:       . Bey gave her sister a huge hug before running off stage to big applause from the crowd. &amp;quot;Give it up for my favorite dancing partner and my favorite person in the world, my sister, Beyonc\u00E9,&amp;quot; Solange shouted. But Beyonc\u00E9 wasn&amp;#039;t the only surprise performer from the Carter fam at the festival last night. Her husband, Jay Z, made his own appearance with Nas, singing &amp;quot;Dead Presidents II&amp;quot; and &amp;quot;Where I&amp;#039;m From.&amp;quot; Puff Daddy/Puffy/P. Diddy/Diddy/Sean Combs (we can never keep up with him on the name front) also emerged from wherever he&amp;#039;s been hiding himself lately to do &amp;quot;Hate Me Now&amp;quot; with Nas later in the set.      Meanwhile, not to be outdone by his fellow Coachella acts, Pharrell had some famous guests of his own. After apologizing for not being on top of his game because of all the dust, the singer was joined onstage by Gwen Stefani (who wore a LAMB jumpsuit, no less), who he introduced as the &amp;quot;incredible, historical, most important, incredibly talented, fucking awesome, rad girl in the world.&amp;quot; The two did &amp;quot;Hollaback Girl,&amp;quot; in what was obviously a b-a-n-a-n-a-s performance:      Nelly, Busta Rhymes, the Puffster (you&amp;#039;re welcome for that one, Diddy), and Snoop Dogg also joined Pharrell, but the most unsurprising guest star of the night? Pharrell&amp;#039;s now signature Vivienne Westwood hat, because that is now a thing that despite dust storms, extreme temperatures, and all reason is never going to die.
