Sandra Bullock  held onto her son Louis's hand as they stepped out of their NYC hotel yesterday. She's in the Big Apple with her 2-and-a-half-year-old while taking care of press for her upcoming comedy The Heat. Sandra had a full day of interviews on Saturday and then hit the red carpet in a laser-cut leather dress for the film's premiere on Sunday. She and costar Melissa McCarthy got goofy for the cameras  and talked to us about their foul mouths in the film. Melissa revealed that she doesn't actually swear as much in real life but that Sandra "swears like a drunk sailor."  Promotions will continue in the run-up to the release this Friday — it's just one of many Summer movies you have to see !
