It could have been any house on this suburban stretch of Staten Island, with a well-worn basketball hoop outside and a sign out front warning, “Beware of Dog.” But here one wintry February afternoon Vinny Guadagnino, the former “Jersey Shore” star, was pacing from room to room of the home where he grew up, now the site of his new MTV talk show, as he awaited a visit from the pop star Kesha.
“Don’t mess this up for me, please,” Mr. Guadagnino begged his mother, Paola Giaimo, and sisters, Mariann and Antonella Guadagnino, who were sitting in the living room amid a home decorated with various ornaments, crucifixes and a map of Sicily. “Don’t do anything.”
A cameraman followed him to the front porch, where a second cameraman awaited and from where he could see Kesha’s black S.U.V. “She’s here, she’s here, she’s here!” Mr. Guadagnino said, rubbing his hands together with nervous energy.
In an upstairs bedroom that had been converted into a television control room the “Jersey Shore” executive producer SallyAnn Salsano watched him on monitors and called out instructions through a microphone.
