You don't suppose that half the reason for dropping them is that Lipton took one look at that fat pig of a lead singer and decided that she promoted a "healty way of living" about as well as the late John Belushi?
She's not so big really, she just looks chubby standing next to those two Doublemint Twins (Thank you, Dennis Miller). Plus, when they were nude on the cover of Entertainment Weekly, everybody knew Natalie had been airbrushed to heck and gone because her belly looked like it came off of Britney Spears.
