Blake Lively was very busy on July 14. She was at another function earlier before attending The Best of Baseball & Music and Vitaminwater party. Since she had to do party hopping from one venue to another, Blake did not have time to change her attire. Her black jumpsuit looked casual and carried her from one function to another effortlessly. She showed plenty of her sexy legs. She had attended the premiere of The Dark Knight with her boyfriend and co-star Penn Badgley.
