Britney broke the news on a surprise appearance on the Late Show with David Letterman this afternoon. It will air tonight, but you can already watch the end of the interview, including the confirmation, here. "Don’t worry Dave, it’s not yours!" Britney laughed. "Oh. Well, I think that’s good for the both of us," Dave responded. "So we’ve established now that you are in fact pregnant, is that right?" "Yes sir," replied Britney. Us Weekly originally reported the pregnancy last month. According to their sources, Britney is about 20 weeks along, with the baby being due October 1st or 2nd. The new baby will join son Sean Preston, 7 months, and half siblings Kaleb, 21 months, and Kori, 3 1/2, from Kevin’s previous relationship.
