23 Stars You Didn't Know Were Adopted

Melissa was born in LA in 1964. One day later, she was adopted by actor and comedian Paul Gilbert and his wife, actress Barbara Crane. It was these Hollywood connections that helped Melissa land the role of Laura Ingalls on Little House on the Prairie (her adopted brother Jonathan also starred on the hit show). Her parents divorced when she was 8, and her mother remarried and gave birth to Melissa's half-sister Sara Gilbert, who starred on Roseanne and is now married to music producer Linda Perry.
