The celebrities came out for Kanye West's Glow In The Dark Tour party held at Club Goa...infamous for being the scene of Lauren Conrad and Heidi Montag's showdown on Monday's episode of The Hills.  Who watched that?  I was surprised that the whole thing was such a big deal.  I would have thought that LC would be capable of at least just sitting at a table with Heidi for a little while...it's not like they had to talk or anything!  What do you think, was Lauren overreacting or was Heidi overstepping her boundaries by going to sit with the group?Click on thumbnails to see pictures of Kim Kardashian, Kanye West, Jay-Z, Kristen Cavallari, Wilmer Valdarrama, Brody Jenner and Michael Johns....that's quite the mix!WENN
