Testosterone-crazed maneater Sienna Miller has reportedly sunk her claws into another unsuspecting cad. The newly-single actress, who recently split from married lover Balthazar Getty, has been spied “making time” with star Josh Hartnett in various pubs and restaurants around London for over the course of the past week.

“They definitely looked like a couple,” says one onlooker. “At one point, they were holding hands across the table, but they quickly hid them underneath. They looked really cozy as they dined, gazing into each other’s eyes, smiling and laughing.”
