Photos of Pete Wentz, Ashlee Simpson, Miley Cyrus, Pink, Anna Faris, John Norris at FNMTV and Lollapalooza

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.
