The TV host-and-model - who tied the knot with the former 98 Degrees singer in front of just 35 friends and family in an intimate Caribbean ceremony on Necker Island last month - hasn't seen her estranged mum Helen Bondoc since she was abandoned by her at the age of nine and didn't tell her she was getting married.
Helen explained: "I didn't have a clue that Vanessa was getting married. We last spoke about 12 years ago, on the phone. I just wanted to talk to her and tell her everything straight about my life. But I still think about her all the time, and I still love her dearly.
"She's changed so much, though I can still see that little scar on her forehead from where she picked at her chicken pox when she was a child."
The 57-year-old former strip club waitress is hopeful about forming a relationship with Vanessa - who was brought up by her father, Vincent Minnillo - in the future, and would like to see her grandchildren grow up should Nick and Vanessa have kids.
Helen added to America's Star magazine: "It would be nice to have a relationship with her now, but I don't know how she'd feel if I called her.
"It would be a happy occasion to meet my grandchildren. Whatever she's doing today, I hope she's happy with this man and that he treats her well. She's still my little girl."
