A source said: "Brad has literally got down on his knees to beg Angelina to change her mind, but she laughs pulls him to his feet, kisses him and says, 'Let's not ruin something so perfect.'"
She is wary of marriage after her previous marriages to Jonny Lee Miller and Billy Bob Thornton ended in blood and tears. Brad feels like the only way he can hold on to Angie is to make it legal.
