Singer Olivia Newton-John and her nephew will be part of the crowd walking at the 500 Festival Mini-Marathon in May.

The "Grease" actress and Firestone Indy Lights driver Emerson Newton-John will lead the "walk within the Mini" to help promote their Pink and Blue for Two charity, which raises awareness for breast and prostate cancers.

Others are invited to walk with them to support the cause.

"The 500 Festival has a great history of providing charities with an opportunity to raise funds through participation in the Mini-Marathon.@ We are particularly excited to continue that tradition by supporting the PB42 organization with a unique platform for their first ever awareness walk,"@500 Festival President and CEO Bob Bryant said in a release.

Emerson Newton-John is co-founder of the campaign and his aunt, who's a breast cancer survivor, is the ambassador.
