Katy Perry Without Cloth: The hottest place to be this weekend is in San Diego for the 2010 Comic-ConNina Dobrev tweeted, "San Diego/Comicon here we come!" But, no one seemed more excited for the festivities than "Glee" star Chris Colfer who told fans,

"This nerd can't wait for Comic-Con! Have I ever mentioned how odd it is meeting someone you used to have an action figure of?"

Whether or not you're on your way to Comic-Con, you can still give a listen to Katy Perry's latest super-catchy tune (which of her songs aren't though?),

"Teenage Dream." Last night Katy joked about the cover (pictured), "My alternate album cover for Teenage Dream... Are you glad I went with the 1st? " But, she was all business today writing, "My new song, 'TEENAGE DREAM' just invaded airwaves! It's on ITUNES today!" The song already found a fan in actress Kat Dennings who tweeted, " 'Teenage Dream' makes me wanna fall in love...damn this girl writes the hits!
