Tinsley Mortimer is busy casting herself as “the innocent victim of bad romances” and plotting her Manhattan comeback after joining “The Real Housewives of New York City.”

Page Six exclusively revealed the former top Manhattan socialite-turned-Palm Beach hot mess, 41, has been filming the Bravo series around town, and she’s using the show for redemption.

The former wife of Topper Mortimer made headlines in April after being arrested in Florida for trespassing at the home of sometimes-boyfriend and sugar heir Alexander “Nico” Fanjul, 30.

It was later exposed by The Post that Mortimer had been in an allegedly abusive relationship with Fanjul for years — though Mortimer never pressed charges and Fanjul’s mother denied any allegations, calling Tinsley “insane.”

An insider said of Mortimer, “She is using the show to plot a comeback and ‘get the truth out there.’ Tinsley knows she’s made some wrong choices, and fallen for the wrong men, but once again she’s back, she’s single, and looking for love. But while once her life seemed to be coated in gold, now things are a struggle.”

The insider said Tinsley will be seen on the show making her return to Manhattan society, trying to get other cast members to set her up on dates with wealthy suitors while saying she’s best friends with her ex, who’s now engaged to designer Tabitha Simmons. Producers have even moved her in with Sonja Morgan, sources say.

A source close to the show said, “They just started filming and don’t know what the storylines will be yet.”

But we’re told Fanjul’s lawyers will be watching closely because another source said of Tinsley, “She has to talk about how she hit a low. This is her comeback story.”

A rep for Mortimer said, “There is no truth to these rumors.”

A Bravo rep did not comment.

In Harper’s Bazaar, Mortimer said of her return to New York, “My friends are here, my life is here, and I just want to get back to it. I walked away from it, and I want it back. And I think I deserve it back.” She’s been seen filming with other cast members at Beautique and Jue Lan Club.
