Talk about an out-of-this-world markdown.

Alice Little is hyping a 50 percent discount on “close encounters with her body” from Sept. 20 to 22 during the Alienstock Festival, inspired by the viral Storm Area 51 movement.

“Ever since Alienstock was announced, my email has been blowing up with questions from lascivious alien enthusiasts asking about how they can meet with me while they’re in Nevada,” says a press release by Little, 29, who claims to be the “highest-earning sex worker in the US.”

The 4-foot-8 Ireland native has worked at the Moonlite BunnyRanch for three years and claims her bookings start at $2,000.

While prostitution is legal in Nevada, some counties do not allow it — including Lincoln, where Alienstock is set to take place. That’s why Little is inviting fellow space cadets to visit her at the BunnyRanch in Carson City, a seven-hour drive west, near Reno and the California border.

“In order to provide my fellow E.T. lovers with the full gamut of Nevada freakiness, I’m turning my suite at the BunnyRanch into ‘Area 69’ during the weekend of the event, and offering the discount as a way to celebrate all the true believers out there,” Little says.

She says her calendar is filling up fast — especially for kinky cosplay sessions.

“I have several clients that enjoy alien-abduction role play and all of the titillating probing that goes along with it,” she says, adding that she’d like to experience the real deal herself. “I hope that one day I’ll personally be able to meet an E.T. face-to-face. I’m convinced aliens exist and may have visited our planet.”

Alienstock was spawned by a Facebook event touting plans to “storm Area 51,” which garnered more than 2 million RSVPs. Organizers secured a permit late last month for it to take place the weekend of Sept. 20 in Rachel, where the Air Force’s infamously classified Area 51 facility is located.

A number of businesses and celebrities have pledged to join in on the supernatural soiree, including a Nevada-based mobile strip club, and Food Network chef Guy Fieri even offered to barbecue some “radioactive ribs.”

Two Nevada counties have issued emergency declarations ahead of the event, concerned that water, ice, gas and food resources will sell out and guests will be unprepared to deal with the lack of cell service and bathrooms.

“Whether or not the aliens show, I believe that Alienstock will be an historic event,” says Little.
