Perez Hilton reports that Simpson Wentz verbally attacked her husband’s ex, Michelle Trachtenberg.
The altercation erupted on Monday (June 1) at the Wiltern Theatre in Los Angeles, where Jay-Z and Eminem were performing for a DJ Hero event.
According to several witnesses, there was no prior reason to believe that tensions were brewing between Simpson Wentz and Trachtenberg.
"The evening started off very civilly. Pete and Ashlee had a pleasant conversation with Michelle and her boyfriend for close to 20 minutes," said a source. Simpson Wentz supposedly even showed them some photos of her son, Bronx.
Wentz, who witnessed the scene, was mortified.
