James Van Der Beek Stars In Ke$ha's New Video In Today's Tweet Dreams

James Van Der Beek + Ke$ha + Unicorns. That, dear Crushers, all adds up to one epic music video. The vid for Ke$ha's latest single, "Blow" (pictured), premiered today, and as Ryan Seacrest noted it wasn't just the pop star's fans who were digging the crazy clip, "Dawson's Creek fans are freaking out - James Van Der Beek is in @KeshaSuxx's new video: http://bit.ly/eZGoUm." James himself took to his Twitter to discuss the four-plus minutes of mythical creature madness, "Ever wonder what would happen if @keshasuxx & I fought a gun battle among Unicorns? Wonder no more."

But it wasn't all unicorns and rainbow guns around the Twitterverse today. "The Vampire Diaries" star Ian Somerhalder got real with his fans when he worried about the fate of the show against ratings giant "American Idol." Ian wrote from his page, "Is American Idol the death of The Vampire Diaries? Well, viewership apparently says so... Our #'s are SO down:( if U guys like TVD u may Lose it if we don't tune in:(" While "TVD" fans must band together to keep the undead alive, "One Tree Hill" actor Austin Nichols was up for the "AI" challenge, "Looks like American Idol is destroying the other shows. They should put my show up against idol. Our numbers are always strong. CHALLENGE."
