The first trailer for "The Twilight Saga: Breaking Dawn -- Part 1" just made its official debut tonight during the MTV Movie Awards -- and it's filled with romance, thrills and Jacob's abs!

The trailer starts with everyone receiving Bella (Kristen Stewart) and Edward's (Robert Pattinson) wedding invitation, and while some are happy, it's not all smiles -- as Jacob (Taylor Lautner) angrily strips before turning into a wolf.

The clip also shows glimpses of the wedding, the bed-breaking honeymoon and Bella's pregnancy.

The movie opens November 18.

Be sure to come back later today to see more from the MTV Movie Awards -- including red carpet shots of Kristen, Rob and Taylor!
