Celebrity Ashlee Simpson Becomes Ashlee Wentz The singer's name change includes using a hyphenated version professionally By Eileen Finan and Marisa Laudadio Published on May 28, 2008 11:05 AM Share Tweet Pin Email Newly married Ashlee Simpson is changing her name to Ashlee Wentz in honor of her husband, Fall Out Boy Pete Wentz. “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.” The singer, whose May 17 wedding featured an Alice in Wonderland-themed reception, says that privately she’ll go by Ashlee Wentz and professionally she’ll be Ashlee Simpson-Wentz. Pete Wentz says he left the name change decision to his wife. “These decisions with Ashlee and her name are all completely up to Ashlee,” Wentz says. “I want her to do these kinds of things the way she wants to do them.” Still, he admits, he was flattered. “Oh man, I was like upgrade me! You know what I’m saying? The Wentz family, our Christmas card just got upgraded!” he says. “It feels insane. It feels unreal.” Like this story? Click on the Yahoo Buzz! button below to Buzz it up!
