LOS ANGELES - Adult performer Mr. Marcus will co-host a birthday party for mainstream model Elke The Stallion tonight at the Aqua Lounge in Beverly Hills.

Mr. Marcus appeared in a sexy softcore photo spread with Elke that will be featured in upcoming book. Elke posed totally nude with the adult star, a departure from her normal modeling photos, and the shoot was erotic without being explicit, Marcus said.

"She covered her breasts. There was a couple of shots where you don't know if it's happening or not so there is still that eroticism and you can let your imagination go wherever," he said.

Mr. Marcus, who performed with Ryder Skye in the new Vouyer Media production Souled Out today, said several celebrities are expected in the crowd tonight.

"It will be a good networking event," he said.

The club is located at 424 N. Beverly Drive in Beverly Hills, 90210. Doors open at 9 p.m. To RSVP email info@browncrownent.com or call 310.403.7874.
