New York, February 26, 2008 – We were glad to see that Pete Wentz accompanied his girlfriend Ashlee Simpson to her performance at Manhattan celeb hangout Marquee, because he’s always hilarious, on anything from women’s underwear to nudity.  The Fall Out Boy rocker was kind of mellow at first during Tuesday’s late-night Caribou Iced Coffee-sponsored party, but rocked out once Ashlee started performing songs from her upcoming CD, Bittersweet World.  (Ashlee’s song "Boys" includes the poetic lyric: “Use your head, but not that one!  One track mind!”)  Sporting red hair and her diamond promise ring, Ashlee performed four songs.
