Giving birth to Camdenfirst “was the blessing that I needed,” she added. “By the time we got to my daughter, I was ready.”

Today, Vanessa can’t imagine her life without her three children — and she takes pride in the special bond sheshares with Brooklyn.

“She’s super intuitive,very smart and very sweet. To see my little girl, I couldn’t be more grateful and thankful that I was given her and that I get to be her mommy,” she said of her daughter. “They all have these wonderful personality traits, and I love watching them grow and look up to me.”

Vanessa said it’s also moved her to see Nick be the “best daddy” to their little girl.

“If I could intertwine my finger with my arm and my eyes and my legs, that’s what they’re like,” she said. “They are thick as thieves, and I couldn’t be more proud. Her relationship with her dad is going to be the relationship that I believe defines her as a woman.”
