After a long night of fun-filled performances and red carpet madness, the Grammy attendees headed out in LA to hit up the after party circuit. House Of Hype Island Def Jam threw a bash that drew out Ryan Phillippe and Abbie Cornish as well as Kanye who also made an appearance at Jay-Z's party at Katsuya. Gwyneth Paltrow also headed to the restaurant to see her friend Jay-Z who had an awesome on stage collaboration with Chris Martin. Kate Bosworth and Hilary Duff weren't in the show's audience, but the hot blondes were happy to get dressed up for the late night festivities with some of the biggest names of the night.
