McCarthy & Bullock Get Giddy in 'Heat'

By
Sandra Bullock and Melissa McCarthy continue to riff off each other's comedic timing as they promote their new female buddy cop comedy The Heat, in theaters Friday, and ET's Rocsi Diaz can't stop giggling!
Watch the video for the stories behind Sandy's "pig face" family tradition and for Melissa's proper pronunciation of "gi" -- plus get a kick as hilarious Boston broads Jessica Chaffin and Jamie Denbo create some chaos at the junket check-in table!
The Heat casts Sandra as Sarah Ashburn, an uptight FBI Special Agent forced to team up with Melissa's foul-mouthed Boston cop Shannon Mullins. The two couldn't be more incompatible, but when they join forces to bring down a ruthless drug lord, they become the last thing anyone expected: buddies.
