July 16, 2007 -- YET another of DJ AM's relationships has ended, though this time it was he who supposedly showed his modelicious girlfriend of four months, Jessica Stam, the door. Insiders say that unlike AM's last girlfriend, Mandy Moore, who is known for her low-key mindset, "Jessica was extremely high-maintenance." The tipster told us, "He didn't see her because she was always traveling, and when they were together, they would just argue."
