Sandra Bullock donned a sexy black gown to premiere her latest film, The Heat, in London today. She walked the carpet solo since her pal and costar Melissa McCarthy is currently on location in North Carolina filming Tammy. Sandra did have the company of director Paul Feig, who is best known for his work on Bridesmaids, as well as her costars Jamie Denbo and Jessica Chaffin. Although Melissa missed out on the trip overseas, she did get to debut the film at CinemaCon with Sandra earlier this year. We were on the ground at CinemaCon back in April to catch up with the hilarious duo, who shared details about their "love connection" off screen. Sandra will soon bring The Heat back to the States since the comedy is set to hit theaters in the US on June 28.
