The cameras were flashing at the London premiere of The Other Woman on Tuesday — and they didn't miss an angle! They captured all kinds of cute group shots between Cameron Diaz, Leslie Mann, and Kate Upton and snapped one particularly hilarious moment when Leslie grabbed Cameron's backside. Leslie got a whole handful of her costar's behind, and lots of laughs followed. The trio is on a press tour for their romantic comedy, which hits theaters later this month. They've clearly been having fun together since filming last Spring, when Cameron and Leslie looked like they were having a blast as they shot hilarious fighting scenes.
