Ah, Bridget Jones. No matter what poor life choice you've made, rest assured you can always rely on her to beat you to it. In the second trailer for the upcoming rom-com Bridget Jones's Baby, we see the hilarious consequences of an accidentally knocked up Bridget (Renée Zellweger, reprising the role she made famous) and her struggle to decipher who the father of her baby is. Is it new guy Jack (Patrick Dempsey) or old flame Mark Darcy (Colin Firth)? While it's clear no one's really sure, and Bridget's doctor (played by Emma Thompson) finds it more than a bit amusing, the battle between Darcy and Jack for who can be the most attentive dad is a sight to behold.

Given the plot machinations of the last two Bridget Jones movies, it seems Bridget can't catch a break when it comes to her love life. Is she doomed to battle an eternal love triangle? Watch the trailer below.

Bridget Jones's Baby hits Australian cinemas on September 15.
