Singer-songwriter Pharrell Williams was one of the most loved stars on Saturday as he made a little boy’s dream come true! The 44-year-old star offered a ride to his concert to eight-year-old Reef Carneson, who suffers from leukemia, and even serenaded her with his song Happy.

JustJared.com reports that Reef has been in the hospital since he was one, and he has always been a great fan of Pharrell and hoped to meet him one day.  

Since Reef’s immune system is too weak for air travel, Pharrell hired a private car to drive him to the venue. The singer even put them up in a five star hotel, got them tickets and backstage passes.
