Sarah Hyland, who plays Haley Dunphy on ABC's "Modern Family", announced that she recently underwent a kidney transplant.The 21-year-old actress revealed on ABC's "Good Morning America" Monday that she had the surgery in April.

Hyland was diagnosed with abnormal kidney development at the age of nine, which often left her exhausted or in pain. Her health worsened to the point where she needed a transplant, and fortunately her father was a match.

Hyland says she tells her dad, "It's weird — I've got your kidney in me."

She plans to spend "Modern Family"'s summer break recuperating.
