Sexy Playboy covergirl Jenny McCarthy is ruling out marriage to Hollywood star Jim Carrey because she's convinced their love will last forever without the need for a wedding. The model insists that living together is enough for both stars, who have been married before, and she's tiring of wedding and children questions. In an effort to end the media rumors about where the romance is going, McCarthy tells In Touch Weekly magazine, "We're living together ... and we're very happy -- all that's going to be is a piece of paper, really. "What is it a guarantee of? I'll be yours forever? I'll be faithful? Bull! "He (Carrey) is the light of my life and we're more in love now than we have been in our entire relationship." And the mother-of-one insists she doesn't want any more children: "This womb is closed."
