Lindsay Lohan Denies Samantha Ronson Reports

Lindsay did hang out with Sam Thursday night at Le Baron in New York -- but sources tell TMZ, there was no touchy-feely business going on ... it was just two old friends catching up together.

There were reports the two might have rekindled a relationship -- but we're told that's not true ... neither Lindsay nor Sam has plans to reunite romantically.

We're told the two are simply focusing on mending their friendship after a rough break-up in 2009. They began dating on-and-off in 2007.
