As we all impatiently wait for the next batch of the Epstein files to drop, a mystery has surfaced from the old batch … a very puzzling, four-legged (we think) mystery.

Check out this bizarre photo of what appears to be a shaggy pooch stuffed, or sitting, in a garbage bag … which was placed inside a cardboard box.

The pic was buried inside a mountain of documents and visual footage released last month by the Department of Justice as part of the now-stalled rollout of the Epstein files.

The snapshot was overshadowed by all the attention on pics of famous people like Bill Clinton, Chris Tucker and Mick Jagger, but we dug it up for you now.

Now, there is this one clue — a 2003 Vanity Fair article describes a “stuffed black poodle” Epstein had on top of a grand piano in his NYC townhouse.

We did find a photo resembling that pooch in the files — but it doesn’t seem to be the same dog in the mystery pic.

Luann de Lesseps turned the shore of Mexico into her own personal gym … performing acrobatics on the beach with the help of a pal — and flashing her booty in the process.

Watch the video — the reality TV star had a flipping fun time out on the sand during her recent vacation in Tulum … putting her hands down and flicking her body up to playfully stand on her hands.

A man with her holds her legs — so she’s not exactly holding herself up like a circus performer. She did put on quite the show, though … because when her cover-up fell down her body, it revealed her tiny bikini bottoms that left little to the imagination.

The two locked lips in the clear blue water … with de Lesseps later standing to reveal her teeny yellow two-piece bikini.

Renee Graziano says the claim that “Members Only: Palm Beach” is the new “Mob Wives” needs to sleep with the fishes … because “Mob Wives” can’t be replicated.

We caught up with the reality TV star in New York City earlier this week … and, we asked her about some of our social media commenters comparing the two programs after we chatted with one of the show’s stars, Taja Abitbol.

Graziano’s not even entertaining the idea … telling us the women in the show — which follows several ladies as they navigate the hierarchies of Palm Beach high society — aren’t married to mob members, so there’s really no comparison.
