Vanessa Minnillo didn't invite her brother to her recent wedding.
A source told America's Star magazine: "Vincent and Vanessa were really, really close when they were kids. But for whatever reason, she stopped talking with him years ago.
"It hurt Vincent initially, but he's moved on and just accepts it for what it is."
Vanessa's mother, Helen Bondoc, was also not there as the pair haven't spoken to each in 12 years.
When Helen was shown Vanessa and Nick's wedding photos 12 days after their nuptials, Helen said: "Oh my goodness, she's beautiful!
"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.
"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."
