Jenny McCarthy is opening up about the "living hell" she's been dealing with after learning she had severe mold toxicity and mycotoxin poisoning in a sneak peek of Maria Menounos' podcast. "The last time I was here I was literally on my way to the biological dentist because I had gone through six months of living hell," McCarthy, 53, reveals of her medical mystery - that's now been solved - while speaking with Menounos, 47, in Us Weekly's exclusive clip of the host's upcoming "Heal Squad" podcast episode.
