A heart of gold.
On Tuesday, Zayn Malik took to Twitter to help spread the word about one of his biggest fans who's in need of help.
According to Rylee's You Caring fundraiser page, Bilateral Schizencephaly is a very rare developmental birth defect that causes abnormal clefts on both sides of the brain.
As a result of the condition, Rylee also suffers from cerebral palsy.
"Rylee currently can't walk without assistance, and she crawls around our house or we carry her," wrote her family members. "Rylee can say a few words but can't carry on a conversation."
The Sanford family is hoping to possibly simplify their extensive medical expenses with the help of the public. Once Rylee realized Zayn shared her story on Twitter, she couldn't help but smile.
