I've now met actor and rapper LL Cool J on multiple occasions and he has yet to disappoint. He's always been very fan friendly and engaging in small talk when you approach him and has signed multiple items too. He's been a class act all the way.
There was one time when he must have been signing 40-50 autographs between a handful of people, myself included, and someone spoke up and said "Don't worry LL, these aren't going on eBay", to which he replied, "I really don't care what you do with them."
If you have the chance to meet up with him then I'm sure you'll leave with a positive experience.
