Taking to the picture-sharing site yesterday, Megan confirmed her twin sister suffered a broken pelvis, legs, foot and hand.
She began: “I received the most terrifying phone call I’ve ever received in my life on Tuesday evening.
“My twin sister Kathryn was hit by a cement truck while crossing a road in New York on the 7th September.
“After fighting through complex surgery some of Kathryn’s injuries include broken pelvis in two places, both of her legs, her foot and her left hand. She is incredibly lucky to be alive.”
