Did Lindsay Lohan really dump Samantha Ronson?

Lindsay Lohan broke up with her girlfriend Samantha Ronson just before the two were popped by paparazzi leaving the Waverly Inn in New York City on Tuesday night.
I find that hard to believe since both Lindsay and Sam looked awfully happy in aforementioned photos, but you never can tell.
Here's Gawker's story:
"One of our inside New York sources, Guest of a Guest spotted the actress/deejay duo at the Waverly Inn last night, a Gotham hotspot frequented by all of the Big Apple's most in-the-know glitterati. All seemed well enough as they dashed out of a sleek black SUV and past the usual swarm of paparazzi into the restaurant. But then things got ugly! Our source tells us:
"We really did not pay much attention to them once we were seated, except at the end of their meal when Lindsay stood up and stepped/stumbled on [my friend's] foot. Without looking back or apologizing she headed straight out the door. We guess her exit was spontaneous as Samantha was behind her sputtering: 'Are you leaving?' 'Lindsay are you leaving?' 'I guess she’s leaving.' 'She just left!'"
What do you think? Is the lesbian love between Lindsay Lohan and Samantha Ronson over?!
