“I was just so choked up, she was so excited,” Ava Keen, Chalon’s mother, told the Associated Press. The teen was cheerfully tearful during the visit by Diddy.

Chalon, who hails from Sunrise, Florida has fought a form of cancer that produces tumors in her muscles. She and her doctors are exploring the possibility of getting a bone marrow transplant.

Diddy bestowed his gift to Chalon during Chris Evert’s annual charity tennis tournament in Delray Beach. The occasion has raised over $13 million dollars for needy and abandoned children.
