The 33-year-old actress was joined at the event by her Frozen co-stars Josh Gad and Santino Fontana, writers/directors Chris Buck and Jennifer Lee, and “Let It Go” songwriters Bobby Lopez and Kristen Anderson-Lopez.
Noticeably absent was Idina Menzel, who had to fly back to New York City that day to get back to work on her brand new Broadway musical If/Then.
Kristen, Idina, and the Frozen crew performed at a special cabaret concert the night before to promote their hit animated film, which is nominated for two Oscars!
FYI: Kristen is wearing a Prada dress. More Here! »
