Scout Taylor-Compton and Samuel Larsen dated from October, 2011 to January, 2013.
Are they still together as of Nov 2012 they are no longer tweeting each other, but this is the third time they have done this. (stopped tweeting for a couple of weeks.)
Its weird they'd go out together when Sam is a devout christian and Scouts been known to sleep around a fair amount in Los Angeles. It looks like she's using him for his upcoming status, then she'll be sleeping with the next guy that comes along
