Just call her Ashlee Simpson-Wentz. Ashlee Simpson has opted to hypenate her stage name to Ashlee Simpson-Wentz after wedding Fall Out Boy star Pete Wentz in a sunset ceremony in Encino, California ten days ago. When she’s not performing “Ay Ay (Outta My Head)”, “Pieces of Me” or any of her other singles, the pop singer will be legally known as Ashlee Wentz, in honor of her new husband.

“I think that that’s something that a woman should do when they’re marrying a man,” she tells PEOPLE. “It’s a tradition that I think is a great tradition.”
