'Bridget Jones Baby' has a new trailer and fans of the series will finally get their long-deserved sequel. What's motherhood look like for Renee Zellweger's titular character? Well, she's not so sure herself. The plot of this movie revolves around Bridget's pregnancy and the burning question: who does the baby belong to? It could be actor Colin Firth, as seen in previous installments, or newcomer Patrick Dempsey. Jones's diary has now been upgraded to a fancy new iPad, and Sharon Macguire, who directed the movie that started it all, is back to direct this one, which will hit theaters on September 16th.
