Is Tracee Ellis Ross pregnant?

[TMC]

So on last night's Black-ish, Tracee's character, Rainbow Johnson is revealed to be pregnant. Everyone that's ever watched a sitcom knows that a new baby usually signals that the show has jumped the shark; when a "Cousin Oliver" is introduced its usually used as a desperate attempt to revive a dying show that's been on for several seasons. Black-ish is only in its second season and is doing well in the ratings. They also had a storyline last season which made it seem like Dre and Bow were very done having kids, and were more than content with the 4 they had.
