Pamela Anderson is selling her 2007 Range Rover on eBay and it’s all for a good cause. The former Baywatch babe is donating the entire selling price to Sean Penn’s J/P Haitian Relief Organization.

The charitable star is drumming up interest for the effort by advertising the auction on her Twitter page.

"Auctioning off my Range Rover for Haiti," she wrote. "Buy me now!"

While only one bid has currently been placed at $29,999.99 there are still four days until the sale ends and Anderson has even promised to hand the keys over herself if it sells for more than $50,000.

The former Playboy Playmate posted a heartfelt message with her ad in which she explains why she is making the charitable donation.

"All I had to do was look in my perfectly groomed driveway to see I do not need 2 vehicles," she said. "I wanted to be able to share some of my comfort with those that have none.

She also took the opportunity to make a joke about her rocker ex-husband, Tommy Lee.

"A few mild scratches in the driver's side seat due to lending it to Tommy for a month while is impala was in the shop - wallet chains wreak havoc on soft interiors."

Best known for his serious roles and political activism, Sean Penn has been making headlines for his love life more than his movies lately.

The Oscar winning actor went public in July with a new, young mystery girl in July on a Malibu beach, a sexy brunette who some media outlets initially misidentified as Stacey Koplin.

Now Star magazine has exclusively revealed the woman in question is actually 26-year-old Shannon Costello, an aspiring actress and producer from Seattle who first met Penn,51, at a Los Angeles event party in the fall of 2009.
