When asked if she "believes" in marriage, she told German magazine TVMovie: "I like the thought of two people staying together for the rest of their lives. For me, however, this doesn’t need to be sealed with signatures.”
Her alter-ego Bella is set to tie the knot with Robert's character Edward in film 'The Twilight Saga: Breaking Dawn Part 1' – which is set to be released later this year – and the 21-year-old beauty explained she "loves" the wedding dress she has to wear for the marriage scenes.
She added: "I love it! It’s old-fashioned, but that’s exactly what I like.”
Robert recently gave Kristen – who is a fan of vintage jewellery - a $40,000 antique gold and platinum locket with a personalized inscription, which reportedly reads: "Even if you can't see me, my love for you is always there."
The gift also contains photographs of the pair together inside.
