Mara Siegler writes at Page Six:

Sydney Leathers the woman who horndog Anthony Weiner sexted as “Carlos Danger,” torpedoing his mayoral campaign in 2013 — has accused the pervy former pol of being up to his old tricks again, with yet another woman.

Leathers on Thursday posted a scathing review of the recent documentary “Weiner” — which covers the sexting scandal — on Beltway blog Washington Babylon, and in Leathers’ “thumbs down” notice, she writes that Weiner’s “behavior will continue. In fact, I am certain his behavior continues to this day because a woman who claims to be one of his current sexting partners has reached out to me for advice.”

But Leathers — who in 2013 leaked her Weiner story — exclusively told Page Six she’s advised the mystery woman not to go public.

“She was thinking about talking to press,” Leathers told us on Thursday. “I said, ‘You shouldn’t do that,’ which would surprise people… but it was like, ‘look what happened to me. It will impact future employment, relationships with friends and families.’”
