Jen did a quick change out of her Dior and into a Calvin Klein Collection and went from the Governors Ball to the Vanity Fair Oscar party at the Sunset Tower Hotel in Los Angeles. This annual, totally exclusive, star-studded event begins with an intimate seated dinner for 150 then grows as the stars make their way to the bash after the awards. You can check out a video of the party HERE. Jen shows up at the :20 mark for about 20 seconds.
