It looks like Ashley Olsen and her main squeeze Justin Bartha are at it again.
Back in August, Justin and Ashley were seen enjoying a romantic dinner and a little make-out session at Serafina in NYC. They've been an item for four whole months now and things are still going strong.
Ashley, 22, and Justin, 30, were most recently spotted in Vegas partying the night away. Justin is in town working on his next film "The Hangover" and Ashley has been a regular on set.
According to Fox News, at a local hangout, they "couldn't keep their hands off each other. They were rubbing each other, hand-touching and there was barely a break in their conversation."
