22-year-old Stewart and Pattinson attended the world premiere of 'Breaking Dawn- Part 2', at Nokia theatre in Los Angeles on Monday.
The actress trailed behind Pattinson, as the couple made their way to the front of the theatre, stopping to sign autographs for their thousands of fans, US magazine reported.
Stewart donned a daring nude, strapless gown for the event, completing the look with her brunette hair swept to the side in curls, while the 26-year-old actor looked dapper in a dark-green suit and lavender shirt.
At one point, the couple stopped to pose for a picture together.
The 'Twilight' couple have been making the rounds recently to promote the final instalment of the successful franchise but have been tight-lipped regarding the on-again status of their relationship.
