Carmen Electra says her pet name for ex-hubby Dennis Rodman is "Little Choo-Choo" and that she likes to tease the former basketball star mercilessly about his bad-boy behavior. "I have all these little names for him," she tells The Toronto Sun, "but he's mad because all his friends found out and now they tease him. But he is so Little Choo-Choo — he is! He is a little baby."
