The curvaceous star, who is rumoured to be pregnant by singer husband Marc Anthony, was inspired by other unusual smells in her home.
She says, "I said warm yellow cake and a redcurrant candle I had at home and they went away to experiment with those things and see what they could come up with."
But the star humorously insists no real babies were used in experiments. She says, "I don't need those accusations about babies. No babies went into that bottle."
