Ashton Kutcher and Natalie Portman go risque in the new redband trailer for their new film, ‘No Strings Attached.’
Portman and Kutcher play best friends that begin to sleep with each other… to predictable, yet potentially surprisingly funny results. One thing’s for sure: those results are racy.

The film co-stars Mindy Kalig of ‘The Office,’ Jake M. Johnson of ‘Paper Heart,’ Greta Gerwig of ‘Greenberg,’ and Ludacris.
