Britney Spears strips off her underwear to reveal a skimpy dress as she shares snaps of her flirty dresses on Halloween

Britney Spears celebrated Halloween with a small fashion show at her $11.8 million Calabasas mansion for her 42.4 million Instagram followers to enjoy.

The semi-retired pop star left little to the imagination in a completely sheer, side-slit dress with three silver chains draping over her bare hips.

Britney cradled one of her five dogs – a Maltese named Lacey Loo – on her bikini-clad chest in the clip for J Balvin and Willy Williams’ 2017 song “Mi Gente.”

Meanwhile, the 41-year-old Grammy winner showed off significant cleavage below her breasts while wearing a sheer black dress with sexy cutouts in the first of three videos she posted on Tuesday night.

Britney – whose third husband Sam Asghari filed for divorce from her in August – modeled the mesh creation while dancing along to Janet Jackson’s 1993 song You Want This.

She then donned a mini dress with a silver sparkly top as she posed in front of her stripper pole.

Spears then slipped her slim 5-foot-10 frame into a red dress that exposed her arms, abs and legs as she posed in front of her Christmas tree in a clip set to Madonna’s 2012 song “I’m Addicted.”

The “Hold Me Closer” hitmaker’s critically acclaimed memoir “The Woman In Me” has sold 400,000 copies since its release a week ago, according to TMZ.

Simon & Schuster paid Britney a $12.5 million advance (25% of net profits) to write the 288-page book with three “collaborators,” also known as ghostwriters.

Two people close to the project told The New York Times on Tuesday that author Ada Calhoun “helped create the first draft” and author Sam Lansky was “the next to join the team on The Woman In Me.”

“The book was completed with the assistance of Luke Dempsey,” the insider told the magazine about the final author to contribute.

And on Monday, Deadline reported that “buyers are circling Spears’ autobiography to bid for the rights to make a possible limited TV series based on the book.”
