Did Denrele just refer to himself as a "Sister"?

First of all, can we acknowledge the fact that Denrele Edun's sister Jumoke is such a pretty lady? Now  while celebrating his beautiful sister, Denrele stylishly dropped it in that he was a sister.  He wrote;

"In the cookies of life, Sisters are the chocolate chips! All hail @jay4ril my younger sis who SLAYS all day, every day! A perfect Sister I am not; but thankful for the one I've got! JUMOKE DUN...OverFine is worrying you!!! #MySisterBeBadderThanYours #MySisterBeSlayingToTheMax"
