Lebron James big 'Saturday Night Live' appearance is tomorrow. Is the Cleveland Cavalier star forward nervous? It sure doesn't sound like it.

"I'm going to just wing it," said James and added, "I want to make an impression. Just go out there and be original and have some fun."

James isn't the first NBA star wearing number 23 to host the popular show. Michael Jordan hosted the 1991 debut of SNL.

No word on what skits the Cavs star is working on but he was practicing yesterday with his fellow cast mates for the show yesterday.
