Jenna Jameson made quite a fashion statement over the weekend while celebrating her upcoming 39th birthday in Las Vegas.

The former porn star stepped out at Crazy Horse III Gentlemen's Club in a black and white jumpsuit that revealed quite a bit of skin via several panels of sheer material. And her underwear lines were clearly visible.

She paired the look with pastel green hair that is shaved on the left side.  Her outfit seemed more suited for Halloween than a birthday party.

Throughout her XXX-rated career, Jameson made upwards of 50 films, including her most popular, "Brianna Loves Jenna" (2001). Her 2004 autobiography, "How to Make Love Like a Porn Star: A Cautionary Tale," spent six weeks on The New York Times Best Seller list.

Jameson is currently dating MMA fighter Tito Ortiz, and she gave birth to the couple's twin sons in 2009.
