Speaking to Celebuzz, Snooki (real name Nicole Polizzi) recalled Li-Lo and Pauly (real name Paul DelVecchio) getting friendly on a night out in Los Angeles to promote the show's first series.
She said: "It was the first time in LA and I feel like she was flirting with Pauly - and I feel like they made out."
But she dismissed any thought that a romance might have blossomed between the pair, adding: "It was, like, three years ago."
And Snooki also stuck up for Li-Lo, who has been having a tough time of it lately.
"Personally, I like Lindsay," she continued. "I think she's a fun girl and she's made a few mistakes and people think she's the devil for it."
