Luann de Lesseps Flashes Butt While Doing Handstands in Mexico

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.

LdL’s been living it up in the Mexico town recently … packing on the PDA with her new boyfriend Michael Riemerschmid during a swim earlier this week.

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