WHO’S the one person who can turn hilariously foul-mouthed insult queen Lisa Lampanelli into a softie? Pop icon Barry Manilow, reports The Post’s Mandy Stadtmiller. “No one is off-limits – no one except for Barry,” Lampanelli told the Friars Club as Manilow became an Honorary Friar. “He provided the entire soundtrack to my life, and how can you thank someone for that? He’s one of the three people I’ve ever been speechless in front of: [Don] Rickles, [Howard] Stern . . . and then Barry.” Manilow thanked the club for the tribute, adding, “Most of all, thank you so much for not roasting me. I have been roasted every day since ‘Mandy’ came out.”
