Fall Out Boy rocker Pete Wentz regrets piercing his manhood in his youth, insisting it was stupid decision. The bassist, 34, admits he got a little caught up in the rock star lifestyle. Speaking during an appearance on U.S. talk show Watch What Happens Live on Monday (20Jan14), he said, "Have I ever gotten a piercing below the waist? I've had basically everything pierced in my entire life... "I did (have my penis pierced). I was young and dumb and full of wisdom! It's not pierced anymore." Wentz recently revealed in an interview with FHM magazine that he previously had his septum, nose, ears, lips, tongue and nipples pierced, too, adding, "This was all done before I was 22. I've since had them all taken out."
