Among them? Melissa Gorga's song, "On Display."
Apparently, her sister-in-law Teresa Giudice thinks the song – which Gorga wrote and recorded during her first season on the show – may be about her.
"So many people told me that," Teresa tells Cohen in a clip of Watch What Happens Live: NJ Housewives Tell All, airing Sunday (8 p.m. ET) on Bravo.
The issue is in the lyrics about being followed by paparazzi.
"She just had written that song. There were no paparazzi following her," Teresa says. "[My fans said], 'Teresa, everywhere you go there's paparazzi following you.' They're like, 'She wrote that song wanting to be you.' "
Melissa's response: "No. It's definitely 100 percent not [about her]. It's like can anything be mine? ... No one gets credit for 'On Display.' It's my song."
