Justin Timberlake has won the heart of a sick teenager by granting her wish of meeting him.

Emily Sanchez found out she had congenital heart disease and a heart malformation several years ago, and was told in 2012 that she had heart failure - but this year a donor match was found and she had a successful transplant.

According to E!, the young fan met her idol Justin Timberlake through US charity Kids Wish Network and was treated to seeing Mirrors singer Justin's 20/20 show in New Orleans, meeting him backstage and having a day of shopping and dining with her mum beforehand.

Emily, who has credited Justin's music with helping her get through her illness, said of meeting him: "It was amazing! Thank you all so much!"

Her mum Jennifer said: "Thank you Kids Wish Network for granting this wish for my Emily. It was truly a dream come true, she had a wonderful time."
