30 Rock's Tracy Morgan to Host Event

The 44-year-old star of 30 Rock, Tracy Morgan will host the 2013 Billboard Music Awards and said he chose his terms "wisely" when asked about his responsibilities.

"Words take on meaning," he told People, "If I say, 'I'm nervous,' then I'm going to be nervous. If I'm excited, then I can't wait for it to start. People who are nervous can't wait for it to be over. Nervousness is negative to me. Excitement is the way I like to use it."
