Pregnancy rumors have swirled around Khloe Kardashian ever since she revealed that she and her husband, Lamar Odom, really want kids and aren’t doing anything to prevent having them. Those rumors have popped up again, prompting Odom to make a joke out of rebutting them. “She hasn’t told me if she was pregnant,” he said in an ESPN interview. “I probably would be the first to know.” Odom, who has two children (Destiny, 12, and Lamar Jr., 8) with ex-girlfriend Liza Morales, might be busy with other things; the Lakers recently defeated the Phoenix Suns to move on to the NBA finals. Game one against the Boston Celtics is tomorrow.
