16. Heidi Montag
Montag is far more famous for her cosmetic surgeries than her acting skill on TV. In one day, Montag apparently underwent 10 different surgeries, including a rhinoplasty, chin reduction, ear reconstruction, lip fill, botox, breast implants, butt implants and liposuction. Montag looked like a completely different person when she made her public debut after surgery, especially since she went from a B-cup to an F-cup. Montag eventually had breast reduction surgery because of neck, back and arm problems. No one will forget Montag???s plastic surgery, horror story.
