Jessica Simpson and besties CaCee Cobb and Ken Paves are using their celebrity status for good, promoting a new initiative that aims to deliver 50,000 pairs of shoes to Haiti in 50 days.

The program is called 'Soles4Souls'. For a $5 donation, people can provide two pairs of shoes to earthquake victims in Haiti - yep, it's just $2.50 per pair of shoes.

Simpson tweeted details of the appeal out to her 2.1 million followers, while her co-stars Cobb and Paves - the trio present the VH1 reality show, The Price of Beauty - drummed up support by letting their 30,000-odd combined followers know about the program.

"Let's all do everything we can for the tragedy in Haiti," Simpsons says.
