Abby and Brittany, 25, have been called one of the sexiest Siamese twins. They are dicephalic parapagus twins, meaning that they are conjoined twins who each have a separate head, but share one body…and what a body! Right?
They have several separate vital organs: a separate heart, stomach, spine and spinal cord. But they share their arms, breast, ribcage and legs. They also have a reality show on TLC called Abby & Brittany. They both went to college and have B.A. degrees and are considered one of the most successful conjoined twins in the world
