Ashlee Simpson was seen instigating a fight with her husband, Fall Out Boy’s Pete Wentz, Saturday, reports Perez Hilton. Wentz was celebrating the one year anniversary of his bar, Angels & Kings, following a performance by his band at the Blink 182 concert in his hometown of Chicago.

Eye-witnesses say an extremely drunk Simpson went up to her husband in the bar’s DJ booth and yelled at him to leave. “They fought,” reported a witness, ”she told him he was horrible in front of a whole group of people and made him leave his own party early. So they make a scene and leave the bar.”

The couple reportedly continued to fight once outside the bar, and Simpson chased a passerby down the street and forced him to erase photos he’d taken of the incident. Security then escorted the pair back to the corner where their driver picked them up in an SUV.

This follows an incident where Simpson publicly berated Wentz’s ex-girlfriend, Michelle Trachtenberg.
