Pattinson, Stewart and Lautner were on the red carpet in downtown Los Angeles for the premiere of Twilight: Breaking Dawn: Part One, the fourth in the series of films that have broken box-office records around the globe.
And the normally camera-shy Stewart not only beamed for the cameras alongside her boyfriend and co-star Pattinson, but also dressed to impress with a gown slit daringly to the thigh.
This film sees newlyweds Bella and Edward continuing to face the threats from the wolves and enemy vampires of old, as well as new challenges with the arrival of their child.
Some of the film's biggest secrets have been kept under wraps, with Kristen Stewart reporting that she was stowed away for what felt like months so that nobody saw her character's wedding dress before it was revealed on screen.
Pattinson and Stewart have long kept silent on their off-screen relationship, but rewarded fans with big smiles and more evident signs of mutual affection than we have seen previously. Stewart recently admitted to having a relationship with "a British man" - well, that's a start.
Producers have taken the same lucrative path as Harry Potter bosses in splitting the final book of the series into two films. Breaking Dawn: Part One is on release in the UK from Friday, and fans will have to wait until next year to see the grand finale on screen.
