No one can say Sandra Bullock's ex-husband doesn't move on fast. Days after going public in Sin City with his new girlfriend, Kat Von D, Jesse James plans to introduce her to his three adorable children, including 6-year-old Sunny.

"Jesse wants to get back to normal as quickly as possible and seems to be swapping out Sandra for Kat," a friend of James tells me. "He likes the routine of having a partner, someone who is always around and can help him out raising his kids. Would he rather be with back with Sandy? Of course. But finally he knows she will never forgive him."
