Here is a caption from some Kevin pictures from April 27th:

Kevin denied the fact that his popstar wife Britney is pregnant with their second child. When asked about the pregnancy Kevin said “I dont know what you are talking about”. Also Britney Spears security is seen picking up some flowers for the pregnant popstar at a local supermarket.
