2009 didn’t start out well for Lindsay Lohan and Samantha Ronson. Our airport spies say they got into another nuclear fight — this time at Miami International Airport.

We’re told it started in the American Airlines Admirals Club. Once on the plane, as one person put it, “Lindsay was so inconsolable the flight attendants asked if she’d like to disembark.”

We’re told there was lots of crying, tears, etc.

It comes a few weeks after another epic fight Lindsay and Sam had at Sam’s Hollywood Hills home. The screaming (and glass-crashing) was so loud it kept neighbors up.
