The French actress - who split from long- term partner Johnny Depp in June after 14 years with him - dislikes the term "soul mates" as she feels giving a term to a significant other doesn`t allow for the fact relationships constantly evolve.
She said: "I believe in love and I believe in wanting to make it last.
"But as soon as you start to say: `Here`s my soul mate`, it feels like you`re done. Love is a constant, evolving emotion. And the fact of putting a title on it, whether it`s your husband or your wife or your soul mate, then it seems like you know the end of the book. And I don`t like to know the end of the book or the movie."
However, despite her views, Vanessa - who has children Lily-Rose, 13, and Jack, 10, with Johnny - admits being described as someone`s soul mate is a "beautiful" thing.
She added to W magazine: "But I mean it`s beautiful when one day someone tells you you`re their soul mate - it makes you feel good."
