I suspect that Lex is a woman. "Abs!" you may cry. But alas, having abs does not give you an hour glass figure. For skeptics, I prepared this little image:
Lex's waist and most of his chest literally click into position in Beckys silhouette.
P.S:
Yes I turned Lex around.
No, I did not (intentionally) change his figure.
Yes the head and arms were removed to avoid confusion.
