Sean "Diddy" Combs made a surprise visit to Chris Evert's charity tennis tournament to meet a teenage cancer patient.

For Chalon Keen, 17, of Sunrise, who has been fighting for two years a cancer that creates tumors in her muscle cells, Saturday's visit was a dream come true.

Chalon, a patient at the Chris Evert Children's Hospital at Broward General Medical Center, met Combs through the Make-A-Wish Foundation.

Ava Keen, Chalon's mother, said her daughter cried the whole time. The meeting lifted the teen's spirits as she and her family prepared to travel to the Mayo Clinic in Minnesota to undergo tests for a possible bone marrow transplant.

"I was just so choked up, she was so excited," Ava Keen said.

Evert's annual event has raised more than $13 million to fight drug abuse and help neglected and abused children in south Florida.

Comedian Jon Lovitz, supermodel Frederique, tennis star Sebastien Grosjean, NBC news anchor Stone Phillips, singer Michael W. Smith and actor Alan Thicke also attended the event.
