Lol, Did MBGN 2014, Iheoma Nnadi Lie About Her Age?

The news booming right now is that the recent MBGN 2014, might be lying about her age. The whole suspicion started after she posted a throw back  photo(above) on her IG page. And with her caption on the photo, she claimed the photo was taken as far back as 2007. Now fast forward to this present day....she is 19 years now, that means she was 12 years of age then. Lol...
Don't even bother checking her IG page because she has already deleted the photo. What do you guys think about this?. Does the photo look like a 12 years old girl?
