-- Ok I am far from liking Britney, but I can also say that you dont have to like Britney and you are free to hate her, but the picture is still pretty very natural because she is pregnant and pregnancy is beautiful.
Whether she did it for any other reasons than just celebrating her pregnancy we don't know....
