Ashlee Simpson made her first post-baby debut Monday night and was out again yesterday for Pete Wentz's "Without You I'm Just Me" art gallery opening in LA. Ashlee's whole family joined in on the fun, including Jessica matching her sister in stripes. Nicole Richie seems to travel with both Madden boys these days, and hopefully she and Joel can pass on some tips to their friends Ashlee and Pete on being a new parent. Pete must be proud of his original artwork with Travis McCoy but especially happy to have all of his friends and family come to support him.
