Last month, Robert Griffin penned his first tweet. He had one request: to help his son Collin, who had just been diagnosed with stage four cancer, meet J. Cole. Robert included a photo of Collin at his first concert just two years ago smiling alongside Bas and his older brother, and tweeted at Bas directly, seemingly in an attempt to try to get his message to someone on J. Cole's team. Not long after Robert's initial tweet, Bas answered, and last night, Collin’s dream came true.

A GoFundMe page set up by Collin’s older brother Austin explains that Collin has been diagnosed with Rhabdomyosarcoma, a type of cancer so rare “that only one person in the U.S. is diagnosed with per day.” Austin goes on to describe Collin as “by far the most caring, compassionate, loving individual I've ever met in my life.”

“He will go out of his way to help anyone in need at anytime and he never fails to put a smile on your face,” Austin wrote. “He's been so extremely strong so far and I know this is an uphill battle that we're going to win.”

It looks like Collin not only got to go to a J. Cole concert, but he also went backstage and spent some quality time with the rapper. His father posted a series of photos from the meet. 

Robert told Complex that J. Cole and Bas are “incredible human beings” and “the more people that know how genuine and amazing they are the better.”
