No Strings Attached movie trailer: Ashton Kutcher and Natalie Portman have sex

What starts out as a predictable 'can you have sex without love' trailer, moves into steamy territory when Natalie Portman and Ashton Kutcher start getting it on.

The two play friends in No Strings Attached who begin to sleep together and try to keep their feelings out of it.

Yeah, it sounds pretty predictable, but might actually be kind of funny since it also stars The Office worker Mindy Kalig and Ludacris.
