Gisele Bundchen has put on 15 pounds since giving up smoking.The Brazilian supermodel says she is enjoying food so much more since kicking her habit.She revealed: "When you stop smoking you gain weight because food tastes better than when it tasted like an ashtray."It was recently claimed the beauty was pregnant with American footballer Tom Brady's baby after she was seen with what appeared to be a baby bump.While her family were quick to deny the claims, Gisele - who previously dated actor Leonardo DiCaprio - has made no secret of her desire to have children soon.She revealed: "Everybody is different, but for me, having a family will be my greatest achievement."When you have a family that you can raise the way your parents raised you then I think you have succeeded. I have that dream.

"I don't know when it's going to happen. Everything in life has to be planned. I'm very old-fashioned. I believe in being married and going to your husband and saying, 'Let's have a kid'."
