Why did she LIE?

While scrolling through NecoleBitchie.com I saw that she posted a video of Neffe and her bestie friend/stylist. Neffe them posted the video and on the video she clearly states that she is indeed pregnant with a little girl from her soon to be husband Sollow! So why did she tell sister2sister magazine that she wasn't? I personally don't care either way btu didn't she know the secret was gone come out when she dropped that load? What kind of Tom foolery is she on?
