Pete Wentz and Ashlee Simpson took their hipster accessories to the stage at Ren-mar Studios in Hollywood for FNMTV on Friday, where they introduced Miley Cyrus — who offered herself up as a babysitter and even found the time to make a home video with Pete. The couple then headed to Lollapalooza with the likes of LL and Samantha, and partied it up at Pete's Angels & Kings in Chicago on Saturday night. Ash and Pete clearly do a lot of traveling, so it's no surprise that Pete is already talking about making their baby a little jetsetter by bringing him/her on tour.
