Wearing socks but no shoes, with no make-up and her hair looking unbrushed, Emma literally threw up on her way into a friend's home.
Maybe the 21-year-old was just worn out.
Late last month, she partied at the Coachella Music Festival.
On May 1 she attended the Shops at Target launch party in New York. On the 3rd, she was at the Hicks premiere, and on the 7th, she was the belle of the ball at the Metropolitan Museum of Arts' annual gala.
Flying back to L.A., the Wild Child star went to Nylon magazine's Young Hollywood party on May 9 and hit the red carpet for the opening of David Yurman's new flagship store in Beverly Hills on May 10.
Emma will next be seen opposite John Cusack in a movie with a very fitting title -- Adult World.
