Paula was not pregnant, and she isn't pregnant now. Robin's brother Brennan is the one expecting.
A while back MTO dropped the ball and said that she was pregnant after pictures in a very unflattering baby-doll dress were posted. A few weeks later pictures of her in hot pants and a skin tight white t-*** made the rounds, and instead of apologizing for making the wrong call MTO said that she had a miscarriage. They even tried to throw Essence under the bus by saying that Essence originally stated that she was pregnant.
So instead of just admitting that they *** up, MTO insists on sticking with the whole miscarriage lie.
If anything Paula's had every reason to smile from 2006 on. Her husband's career is on track, she's got back to back movies lined up, and she's about to be an aunt. What isn't there to smile about?
