X17 EXCLUSIVE - Lindsay Lohan And Samantha Ronson Hook Up During Second NYC Rendezvous

Lindsay Lohan and Samantha Ronson are becoming inseparable again!

The former lovers met up at Cabin Down Below in New York's East Village Wednesday night and a source tells X17online.com exclusively, "they were going hard!" Whoa!

After Lindsay stopped by the Lifetime up-fronts earlier in the day, she headed back to the Mercer Hotel to prep for an evening on the town. She donned her infamous black leggings, leopard-print platform heels and a black leather jacket and taxi'd to dinner at Rubirosa, a pizza joint in Nolita.

Braving the rain, she headed east to a bar where she and Sam had agreed to meet up and apparently, fireworks went off for the former couple.

"Sam and Lindsay were together all night and were totally inseparable. They were holding hands at the table, laughing, and back to their old selves again. It was total deja vu," our source tells us.

This is the second time in a week that Sam and Lindsay have reunited in New York ... will they bring their love back to LA???
