We're finally getting a look at Bella and Edward exchanging vows in the trailer for The Twilight Saga: Breaking Dawn - Part 1.

The extremely intense trailer begins with a glimpse of their wedding ceremony, a hardcore love-making session ... and ends with just a peek at Bella giving birth.

Robert Pattinson, Taylor Lautner and Kristen Stewart are certainly giving very grown-up performances in this flick.

The movie hits theaters on November 18, and we'll admit, we're counting down the days!
