Britney Spears has confirmed she'll perform a "surprise" concert in Las Vegas Friday night at the Palms Casino Resort Rain Nightclub, which will be filmed for an upcoming MTV special.
"Looks like my little secret isn't a secret anymore. Whos coming to watch me take the stage TONIGHT at @RainLasVegas at @PalmsLasVegas? -Brit" she posted on Twitter Friday (Mar. 25) afternoon.
Shortly after, she added: "You're all invited. Be there or be square bitch! -Britney"
Her manager, Adam Leber, tweeted: #BritneySpearsPalms, which briefly became a Twitter trending topic.
People.com reports she'll hit the stage twice: once at 8 p.m. Friday in a ticketed event, and again at midnight for a performance that will be open to the public. The "Jersey Shore's" Pauly D will DJ.
Spears' seventh studio album, "Femme Fatale," drops Tuesday.
