TMZ: Joe Simpson got all thugged-out Sunday night in Vegas, when a security guard allegedly shoved his daughter Ashlee into a wall. Rush & Molloy report that Ashlee, boyfriend Pete Wentz and Joe were trying to maneuver their way out of a nightclub when Wentz got shoved by a security guard, "knocking Ashlee against a wall." That's when Big Joe went nuts and tried to protect Ashlee, making that throat-slitting gesture in the process. "When somebody messes with my baby, then it's over!" he told R&M. Ever the classy guy, Simpson said the fracas started because the bouncers were "just mad they make $12 an hour." Unlike getting paid a few pennies more by your own daughters.
