Stewart would love to do 'New Moon' again

Kristen Stewart knew when she met the perfect person for her.

The 22-year-old actress - who recently reunited with her boyfriend of four years Robert Pattinson, 26, after her "momentary indiscretion" with her married 'Snow White and the Huntsman' director Rupert Sanders in August - admitted she isn't sure what she finds attractive but knows when she likes someone.
